Book Synopsis Progress in Ferromagnetism Research by : V. N. Murray
Download or read book Progress in Ferromagnetism Research written by V. N. Murray and published by Nova Publishers. This book was released on 2006 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferromagnetism is a form of magnetism that can be acquired in an external magnetic field and usually retained in its absence, so that ferromagnetic materials are used to make permanent magnets. A ferromagnetic material may therefore be said to have a high magnetic permeability and susceptibility (which depends upon temperature). Examples are iron, cobalt, nickel, and their alloys. Ultimately, ferromagnetism is caused by spinning electrons in the atoms of the material, which act as tiny weak magnets. They align parallel to each other within small regions of the material to form domains, or areas of stronger magnetism. In an unmagnetised material, the domains are aligned at random so there is no overall magnetic effect. If a magnetic field is applied to that material, the domains align to point in the same direction, producing a strong overall magnetic effect. Permanent magnetism arises if the domains remain aligned after the external field is removed. Ferromagnetic materials exhibit hysteresis. In 2004, it was discovered that a certain allotrope of carbon, nanofoam , exhibited ferromagnetism. The effect dissipates after a few hours at room temperature, but lasts longer at cold temperatures. The material is also a semiconductor. It is thought that other similarly formed materials, of boron and nitrogen, may also be ferromagnetic. This new book rings together leading research from throughout the world.

Book Synopsis Band-Ferromagnetism by : K. Baberschke
Download or read book Band-Ferromagnetism written by K. Baberschke and published by Springer Science & Business Media. This book was released on 2001-08-28 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascinating phenomenon ferromagnetism is far from being fully understood, although it surely belongs to the oldest problems of solid state physics. For any investigation it appears recommendable to distinguish between materials whose spontaneous magnetization stems from localized electrons of a partially ?lled atomic shell and those in which it is due to itinerant electrons of a partially ?lled conduction band. In the latter case one speaks of band-ferromagnetism, prototypes of which are the classical ferromagnets Fe, Co, and Ni. The present book is a status report on the remarkable progress that has recently been made towards a microscopic understanding of band-ferromagnetism as an electron c- relation e?ect. The authors of the various chapters of this book “Band-Ferromagnetism: Ground-State and Finite-Temperature Phenomena” participated as selected - perts in the 242nd WE-Heraeus-Seminar (4-6 October 2000) held under almost the same title in Wandlitz near Berlin (Germany). It was the second seminar of this type in Wandlitz. (The ?rst in 1998 dealt with the complementary topic of the physics of local-moment ferromagnets such as Gd). Twenty-six invited spe- ers from ten di?erent countries together with ?fty-?ve further participants, who presented contributions in form of posters, spent three days together discussing in an enthusiastic and fertile manner the hot topics of band-ferromagnetism.

Book Synopsis Recent Advances in Rock Magnetism, Environmental Magnetism and Paleomagnetism by : Danis Nurgaliev
Download or read book Recent Advances in Rock Magnetism, Environmental Magnetism and Paleomagnetism written by Danis Nurgaliev and published by Springer. This book was released on 2018-08-14 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a collection of papers presented in the International Conference on Geomagnetism, Paleomagnetism and Rock Magnetism held in Kazan (Russia) in October 2017. Papers in this book are dedicated to the study of the geomagnetic field through most of the Earth's history as well as planetary and meteorite magnetism, and magnetic signatures of terrestrial impact craters. Recent studies, summaries, and reviews include: 1 - theory of the geomagnetic field, its generation and variations; 2 - experimental data on the geomagnetic field changes; 3 – studies of rock magnetism; 4 – paleotectonic reconstructions and paleoceanography; 5 – magnetostratigraphy; 6 – extraterrestrial magnetism. Summary reports and reviews will be presented by the world’s leading experts in the field of geomagnetic studies. Such workshops held by Academic Council have become traditional. They are always attended by leading professionals from Russia, CIS and non-CIS countries. In addition to discussion sessions focused on recent studies and findings, lectures on some basic concepts of geomagnetism will be delivered by leading Russian and foreign scientists

Book Synopsis Introduction to the Theory of Ferromagnetism by : Amikam Aharoni
Download or read book Introduction to the Theory of Ferromagnetism written by Amikam Aharoni and published by Clarendon Press. This book was released on 2000 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book is the second edition of Amikam Aharoni's Introduction to the Theory of Ferromagnetism, based on a popular lecture course. Like its predecessor, it serves a two-fold purpose: First, it is a textbook for first-year graduate and advanced undergraduate students in both physics and engineering. Second, it explains the basic theoretical principles on which the work is based for practising engineers and experimental physicists who work in the field of magnetism, thus also serving to a certain extent as a reference book. For both professionals and students the emphasis is on introducing the foundations of the different subfields, highlighting the direction and tendency of the most recent research. For this new edition, the author has thoroughly updated the material especially of chapters 9 ('The Nucleation Problem') and 11 ('Numerical Micromagnetics'), which now contain the state of the art required by students and professionals who work on advanced topics of ferromagnetism. From reviews on the 1/e: '... a much needed, thorough introduction and guide to the literature. It is full of wisdom and commentary. Even more, it is Amikam Aharoni at his best - telling a story... He is fun to read... The extensive references provide an advanced review of micromagnetics and supply sources for suitable exercises... there is much for the student to do with the guidance provided by Introduction to the Theory of Ferromagnetism.' A. Arrott, Physics Today, September 1997
