Simple Realistic Model of Spin Reorientation in 4f-3d Compounds
نویسندگان
چکیده
This is a simple but realistic microscopic theory of spontaneous spin reorientation in rare-earth perovskites, orthoferrites RFeO3 and orthochromites RCrO3, induced by the 4f-3d interaction, namely, interaction well-isolated ground-state Kramers doublet or non-Kramers quasi-doublet 4f ion with an effective magnetic field 3d sublattice. Both temperature nature spin-reorientation transition are result competition between second- fourth-order anisotropy sublattice, crystal for ions, interaction.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Rare-earth (R) transition-metal (T) compounds of the R(T,M)12-type with R = Y or one of the heavy-rare-earth elements, T = Fe or Co and M = Ti, V, Mo or Si, have been studied at 4.2 K in the Amsterdam High-Field Installation in magnetic fields up to 38 T and at temperatures between 4.2 and 1000 K in other magnetometers. The 4f -3d interaction is derived from magnetization measurements on single...

The dielectric absorption of dilute solutions of aniline, methyl substituted anilines, chlorine substituted anilines, N,N,N',N'-tetramethyl-p-phenylene diamine and 4-aminobiphenyl in various solvents has been measured between 0.3 and 135 GHz. The measurements have been carried out at 20 °C and for some mesitylene solutions also at —30 °C and 60 °C. The absorption curves have been resolved into ...
