CORRELATIONS BETWEEN STRUCTURE AND MAGNETISM IN THIN FILMS AND NANOSTRUCTURES

Autor: P. Le Fèvre, A. R. Fert, H. Jaffrès, A. Midoir, D. Chandesris, J. P. Peyrade, Hélène Magnan

Publikováno v: Surface Review and Letters. :753-761

The bidimensionnal character of thin magnetic films deposited on single-crystal substrates, together with the occurrence of singular crystallographic structures, often confer on these systems electronic properties that cannot be found in bulk solids.

Publikováno v: Materials Science Forum. :949-954

Nanoparticles of cobalt have been prepared by an original method using the decomposition under hydrogen of an organometallic precursor in the presence of a stabilizing polymer. Two colloids (C1, C2) have been obtained by changing the organometallic c

THF solutions of the new organometallic precursor Co(η3-C8H13)(η4-C8H12) react with 3 bar dihydrogen in the presence of polyvinylpyrrolidone (PVP) at three different temperatures, namely, 0, 20, and 60 °C to give colloidal solutions containing fcc

Grain Growth, Microstructure, and Superconducting Properties of Pure and Y2BaCuO5-Doped YBa2Cu3O7-x Ceramics

Autor: Philippe Odier, André R. Fert, Nadia Pellerin, Francisco J. Gotor

Publikováno v: Journal of the American Ceramic Society. 78:2113-2121

Superconducting properties of YBa2Cu3O7–r ceramics have been investigated with the aim of avoiding the weak links that are the principal reasons for low critical current densities in this compound. An efficient grain growth process should be useful

Static and dynamic evidence for a transition at Tc = 0 in the Ising spin glass Fe0.3Mg0.7Cl2

Autor: J.P. Redoules, J. Souletie, J. Vétel, A. R. Fert, Jacques Ferré, J.C. Lasjaunias, D. Bertrand, Rachid Bendaoud

Publikováno v: Journal de Physique. 51:1911-1928

The critical behaviour of the Ising spin glass Fe 0.3 Mg 0.7 Cl 2 has been studied by d.c. magnetisation, a.c. susceptibility and specific heat measurements. We have extended the range of our previous a.c. susceptibility measurements down to 0.02 Hz

Exchange anisotropy in Co/NiO bilayers: time-dependent effects

The time dependence of the exchange anisotropy was studied in Co/NiO bilayers. In order to only observe the relaxation phenomena inside the antiferromagnetic (AF) layer and to eliminate the dynamic behaviour inside the ferromagnetic (F) layer, we hav

Anisotropy of the quadratic magneto-optical effects in a cubic crystal

Autor: Igor Kopriva, Andre R. Fert, Kamil Postava, Dalibor Ciprian, Jaromir Pistora, David Hrabovsky

Publikováno v: SPIE Proceedings.

Magneto-optical (MO) Kerr effects are widely used for a thin film magnetism study. The otpical and MO properties of layer media are described through the permittivity tensor. A cubic crystal is optically isotropic and the linear MO effects are indepe

Linear and quadratic magneto-optical effects in reflection from a medium with an arbitrary direction of magnetization

Autor: Andre R. Fert, Michal Lesnak, Dalibor Ciprian, Jaromir Pistora, Kamil Postava, David Hrabovsky

Publikováno v: 11th Slovak-Czech-Polish Optical Conference on Wave and Quantum Aspects of Contemporary Optics.

Three basic configurations are usually distinguished in calculations of the light propagation in magneto-optical media: polar, longitudinal and transverse direction of the magnetization. In these particular cases the fourth order equations for normal
