Book excerpt: UN LIQUIDE MAGNETIQUE EST CONSTITUE D'UN LIQUIDE CONTENANT, EN SUSPENSION STABLE ET HOMOGENE, DE PETITS GRAINS NANOMETRIQUES D'UN MATERIAU MAGNETIQUE. CES LIQUIDES COLLOIDAUX PRESENTENT EVIDEMMENT UNE FACULTE IMPORTANTE: CELLE DE COMBINER LES PROPRIETES DES DIFFERENTS ELEMENTS LES CONSTITUANT, A SAVOIR LES PROPRIETES DES LIQUIDES ASSOCIEES A CELLES DES GRAINS MAGNETIQUES. LEURS APPLICATIONS SONT DEJA NOMBREUSES DANS LES DOMAINES DE LA MECANIQUE, DE L'INSTRUMENTATION PHYSIQUE, DU GENIE BIOLOGIQUE ET MEDICAL CE MEMOIRE A POUR BUT DE FOURNIR LA MESURE DES PARAMETRES CARACTERISANT L'ANISOTROPIE OPTIQUE LINEAIRE MAGNETO-INDUITE DES LIQUIDES MAGNETIQUES, AINSI QUE LA RECHERCHE D'APPLICATIONS DE CET EFFET. ON SAIT QU'UNE TELLE ANISOTROPIE EST INDUITE LORSQUE LE CHAMP MAGNETIQUE APPLIQUE AU FERROFLUIDE EST PERPENDICULAIRE A LA DIRECTION DE PROPAGATION DE LA LUMIERE. CETTE CONFIGURATION EST APPELEE CONFIGURATION DE VOIGT. LES EFFETS ENGENDRES SONT APPELES DICHROISME ET BIREFRINGENCE LINEAIRES, ET SONT LIES, RESPECTIVEMENT, A DEUX ANGLES ELLIPSOMETRIQUES ET QUE L'ON MESURE.

This book was released on 1996 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL DE THESE PRESENTE L'ETUDE EXPERIMENTALE DES PROPRIETES MAGNETIQUES ET MAGNETO-OPTIQUES DES MULTICOUCHES CO#XNI#1#-#X/M DEPOSEES SUR UN SUBSTRAT DE VERRE. LE METAL D'ESPACEMENT NON MAGNETIQUE EST UN METAL DE TRANSITION (PT) OU UN METAL NOBLE (AU). CES MULTICOUCHES CO#XNI#1#-#X/M ONT ETE PREPAREES PAR EVAPORATION SOUS L'ULTRAVIDE. LA MESURE DES CYCLES D'HYSTERESIS DE CES ECHANTILLONS, EFFECTUEE PAR LE MAGNETOMETRE A ECHANTILLON VIBRANT (VSM) ET PAR LES MESURES MAGNETO-OPTIQUES (ROTATION KERR ET ROTATION FARADAY) ONT PERMIS LA DETERMINATION DE L'AIMANTATION A SATURATION ET LE CHAMP COERCITIF. LES CONSTANTES D'ANISOTROPIE DE VOLUME ET D'INTERFACE ONT ETE DETERMINEES PAR LA BALANCE DE TORSION. CES PROPRIETES MAGNETIQUES ONT ETE DETERMINE DANS UNE GAMME DE TEMPERATURE ALLANT DE 5 A 300K. LA TEMPERATURE DE CURIE A ETE DETERMINEE A PARTIR DE LA VARIATION DE LA ROTATION FARADAY EN FONCTION DE LA TEMPERATURE. NOUS AVONS EGALEMENT ETUDIE LES SPECTRES D'EFFET KERR DANS UNE GAMME D'ENERGIE COMPRISE ENTRE 1,5 ET 5,2 EV. NOUS AVONS MIS EN EVIDENCE LA PRESENCE D'UNE COUCHE MAGNETIQUEMENT MORTE DONT L'EPAISSEUR S'AFFAIBLIT QUAND ON AJOUTE DU COBALT. A PARTIR D'UNE CERTAINE CONCENTRATION DE COBALT, LA POLARISATION DES ATOMES DE PLATINE LES PLUS PROCHES DE CEUX DU COBALT COMMENCE A SE MANIFESTER (X 0,2). LE PLATINE PEUT ACQUERIR UN MOMENT MAGNETIQUE DE L'ORDRE DE 0,3 #B. L'ETUDE DE LA VARIATION THERMIQUE DE L'AIMANTATION A SATURATION NOUS A PERMIS DE METTRE EN EVIDENCE LE CARACTERE BIDIMENSIONNEL DE NOS ECHANTILLONS (T#C#O#X#N#I#1#-#X

BEN YOUSSEF and published by . This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: DEUX OBJECTIFS ONT ETE POURSUIVIS DANS CE TRAVAIL, A SAVOIR: D'UNE PART L'ETUDE DE L'INFLUENCE PREPONDERANTE DE L'ION NON-MAGNETIQUE BI#3#+ SUR LES PROPRIETES MAGNETIQUES ET MAGNETO-OPTIQUES DES FILMS DE GRENAT FERRIMAGNETIQUE MONOCRISTALLIN EPITAXIES SUR DES SUBSTRATS NON-MAGNETIQUES D'ORIENTATION (111) ET D'AUTRE PART L'OPTIMISATION DES CONDITIONS D'EPITAXIE ET DES PROPRIETES SPECIFIQUES DE MATERIAUX OPTO-ELECTRONIQUES POUR UN LECTEUR OPTIQUE D'ENREGISTREMENT A HAUTE DENSITE. A CET EFFET ON MONTRE QUE LA COMPOSITION DES FILMS ELABORES N'EST PAS SUFFISANTE POUR COMPRENDRE LES PROPRIETES DE BASE DU MATERIAU. AINSI ON MET EN EVIDENCE QUE SI LA ROTATION FARADAY DEPEND UNIQUEMENT DU TAUX DE BISMUTH, LES PROPRIETES MAGNETIQUES TELLES QUE L'ANISOTROPIE UNIAXIALE INDUITE K#U#G ET LA MAGNETOSTRICTION #1#1#1 DEPENDENT A LA FOIS DE CE TAUX ET DES CONDITIONS D'EPITAXIE ASSOCIEES A LA SURSATURATION DU BAIN. UNE ANALYSE APPROFONDIE MONTRE LA FORTE DEPENDENCE DE K#U#G AVEC LA VITESSE DE CROISSANCE. L'OPTIMISATION DES CONDITIONS DE CROISSANCE A PERMIS L'ELABORATION DES FILMS PRESENTANT A LA FOIS UNE ANISOTROPIE UNIAXIALE ET UNE ROTATION FARADAY TRES ELEVEE AVEC UNE QUALITE DE SURFACE EXCELLENTE, RESULTATS JUSQU'ICI DIFFICILES A OBTENIR SIMULTANEMENT. LES TRANSDUCTEURS D'ENREGISTREMENT NUMERIQUE A HAUTE DENSITE PAR IMAGERIE MAGNETO-OPTIQUE SONT BASES SUR UN DEPLACEMENT RAPIDE DES PAROIS MAGNETIQUES CE QUI A CONDUIT A UNE ETUDE PREALABLE DES PROPRIETES DYNAMIQUES DE CES PAROIS. A CET EFFET LA FREQUENCE DE RESONANCE DE PAROIS A ETE CORRELEE AVEC LES PARAMETRES INTRINSEQUES DES MATERIAUX MONTRANT UN BON ACCORD ENTRE L'EXPERIENCE ET LE MODELE THEORIQUE. CETTE ETUDE MET EN EVIDENCE PAR AILLEURS UNE DIFFERENCE FONDAMENTALE ENTRE LES VALEURS DES COEFFICIENTS DE RELAXATION DES PAROIS DEDUITS PAR RESONANCE FERROMAGNETIQUE DU MODE UNIFORME ET PAR RESONANCE DIRECTE DES PAROIS MAGNETIQUES

Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
