Alliages magnétiques dilués yttrium-terre rare et scandium-terre rare
(1984) [Tese]This thesis studies the magnetoelastic, transport and magnetic properties of single crystals of yttrium and scandium dopped with rare earth magnetic impurities. From our measurements of magnetostriction on dilute alloys ... -
Etude theorique de quelques proprietes magnetiques, calorimetriques et de transport de systemes d'actinides
(1977) [Tese]Resumo não disponível -
Interações hiperfinas no 150Sm recuando em vácuo
(1974) [Dissertação]A interpretação de dados experimentais de correlações angulares de raios-gama provenientes do decaimento de núcleos pesados recuando em vácuo é ainda um assunto muito discutido. Neste trabalho são analisados os dados da ... -
Structure-induced optical anisotropy in thin films
(1983) [Tese]We consider in this work the contribution of anisotropic microstructure to polarization effects in thin films. The microstructute is pictured by a simple model as composed of identical columns with elliptical cross section ... -
Theory of optical and magnetic properties of deep centers in semiconductors
(1982) [Tese]The present work is concerned with the theory of optical and magnetic properties of deeo centers in various III-V semiconductors. -
Thermoelectric power of some metallic glasses
(1979) [Dissertação]The thermoelectric power of five amorphous metallic alloys have been measured between 4 and 300K. The alloys studied are the commercially available Metglas alloys (specifically Metglas 2204, 2826, 2826A, 2605 and 2605A). -
Thermopower and resistivity of binary metallic glasses
(1982) [Tese]The resistivity and thermopower of two series of amorphous alloys have been measured between 4 and 300K. The alloys studied are MgZn and CuZr, both in the largest concentration range available as amorphous materials.
