Critical Behavior at Surfaces of Strong Coupling paramagnetic Systems Exhibiting a Paramagnetic-Ferrimagnetic Transition
A. Waddahou, M. Chahid, A. Maârouf, F. Benzouine
International Journal of Physics. 2018 6 (4). doi: 10.12691/ijp-6-4-3
Keywords: sublattices, coupling, paramagetism, ferrimagnetism, transition, critical surface effects
Context: The purpose of this work is the investigation of the critical surface effects of two strongly coupled paramagnetic sublattices exhibiting a para-ferrimagnetic transition. The model is of Landau-Ginzburg type, whose bulk free energy is a functi...

Order Parameter Profiles near Surfaces of Super-weak Ferrimagnetic Materials Exhibiting a paramagnetic -Ferrimagnetic Transition
A. Waddahou, M. Chahid, A. Maârouf
International Journal of Physics. 2018 6 (5). doi: 10.12691/ijp-6-5-2
Keywords: sublattices, coupling, paramagnetism, ferrimagnetism, transition, order parameter profiles
Context: ...m of this paper is to determine the full order parameter profiles close to the surface for a system made of two strongly coupled paramagnetic sublattices of respective moments φ and ψ. The material exhibits a para-ferrimagnetic transition at some critical temp...

Structural Order of Clays from Gounioube’s Deposit (Ivory Coast): Study by Electron paramagnetic Resonance Spectroscopy
Jean-Pierre S. Sagou, Séka Simplice Kouassi, Lébé Prisca M.-S. Kouakou, Léon Koffi Konan, Y. J. Andji-Yapi, Thierry Allard
American Journal of Materials Science and Engineering. 2017 5 (1). doi: 10.12691/ajmse-5-1-5
Keywords: clays, kaolin, epr, cristallinity, iron status, structural defects
Context: ... purpose, the behavior of iron and electronic defects related to irradiation damage in these clays is examined by using Electron paramagnetic Resonance spectroscopy measurements, which point out the presence of structural defects in these materials. A deep inspection ca...
