Linear 3d-4f compounds: synthesis, structure, and determination of the d-f magnetic interaction.
A family of [RE2M2L2(BA)6] (RE = Gd, Tb, Dy, Y; M = Co, Ni, Cu, Zn; L = 1,2-bis(2-hydroxy-3-methoxybenzylidene)hydrazine; BA = benzoic acid) complexes were synthesized and structurally and magnetically characterized. The magnetic interactions between spin centers were systematically investigated. The interactions of M-M (M = Co, Ni and Cu) and Gd-Ni/Cu were extracted from the fitting of the exp...
متن کامل4f-3d interaction and magnetic anisotropy in ThMn12-type rare-earth transition-metal compounds
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...
متن کاملProbing 3d−4f Exchange Interactions by High-Field Magnetization Measurements
In a 4f−3d ferrimagnet the molecular field (a net value expressing the relevant exchange interactions) can be determined from high-field magnetization measurements. If the applied field is high enough, it breaks the ferrimagnetic ground state and drives the system towards ferromagnetic order via non-collinear intermediate phases. Magnetization curves of Er2Fe17 singe crystal were measured along...
متن کاملHOW THE KONDO EFFECT CAN EXIST IN Gd INTERMETALLIC COMPOUNDS
Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of Kondo Lattice. We suggest that the conduction electrons have gained local character. It is shown that Kondo effect should be observed...
متن کاملNuclear orientation experiments on cerium intermetallic compounds
2014 Nuclear orientation experiments on In3Ce, Pb3Ce, Sn3Ce show that the first compound is well ordered, that Sn3Ce is a Kondo lattice and that further experiments must be performed in order to confirm the Kondo state of Pb3Ce. A simple interpretation is proposed to explain the behaviour of these abnormal compounds. LE JOURNAL DE PHYSIQUE LETTRES TOME 39, 1 er MARS 1978,
