E. B m z o e t al.: Magnetic Properties and Resonance Study of Gd (Co,)Les composBs Gd(Co,AlI --5)3 avec x 2 0,2 sont ferrimagnbtiques. Les moments magnbtiques moyens des atomes de cobalt dbcroissent si le contenu en aluminium est plus grand. Linverse de la susceptibiliti! magnbtique suit une loi hyperbolique de NBel. Les mesures par rdsonance paramagndtique Blectronique sur le GdAl, montrent que le facteur g = 1,959 et la pente de la largeur de la raie est D H / T = 2,s G/K. Dans les composBs ferrimagnhtiques les valeurs g et D H / T varient avec la tempkrature. Les donndes expdrimentales sont analysdes, dans u n modele qui utilise 1' approximation du champ molBculaire. Finalement nous analysons le comportement magnetique des atomes de cobalt dans les composds Gd(Co,All-x)3. compounds is analysed.
Electron spin resonance investigations of the thermo-oxidative degradation of trans-polypentenamer rubbers, containing various stabilizers, are reported. The dependence of the resonance line parameters on the degradation time and temperature as well as the effect of various stabilizers on the resonance line are studied in detail. The activation energies for the generation of free radicals, the reaction order for the overall generation of free radicals and the associated constant rate, are estimated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
