Anomalous temperature and field behaviors of magnetization in cubic lattice frustrated ferromagnets
A. N. Ignatenko, A. A. Katanin, V. Yu. Irkhin
Thermodynamic properties of cubic Heisenberg ferromagnets with competing exchange interactions are considered near the frustration point where the coefficient in the spin-wave…
Correlation Effects and Non-Collinear Magnetism in the Doped Hubbard Model
P. A. Igoshev, M. A. Timirgazin, V. F. Gilmutdinov +2
The ground--state magnetic phase diagram is investigated for the two-- and three--dimensional -- Hubbard model. We take into account commensurate ferro--, antiferromagnetic,…
Anomalies of transport properties in antiferromagnetic YbMn2Sb2 compound
V. N. Nikiforov, V. V. Pryadun, A. V. Morozkin +1
The low-temperature transport properties (resistivity, thermal conductivity, thermoelectric power) are experimentally investigated for the compound YbMn2Sb2. Large Seebeck coeffici…
Ferromagnetism and transport properties of the Kondo system Ce4Sb1.5Ge1.5
V. N. Nikiforov, V. V. Pryadun, A. V. Morozkin +1
Ferromagnetic ordering with a small magnetic moment is found below 14 K from SQUID measurements for the compound Ce4Sb1.5Ge1.5. The transport characteristics of a number of Ce4Sb3-…
