Thermal conductivity of CdCrSe ferromagnet at low temperatures: role of grain boundaries and porosity
Jiří Hejtmánek, Kyo-Hoon Ahn, Zdeněk Jirák +5
It is unambiguously demonstrated that the low temperature magnon specific heat in a ferromagnet varies as T and the magnon thermal conductivity, due to T - dependen…
The spin-state crossover and low-temperature magnetic state in yttrium doped PrCaCoO
K. Knizek, J. Hejtmanek, M. Marysko +6
The structural and magnetic properties of two mixed-valence cobaltites with formal population of 0.30 Co ions per f.u., (PrY)CaCoO ( a…
Crystal field and magnetism of Pr and Nd ions in orthorhombic perovskites
P. Novak, K. Knizek, M. Marysko +2
Fifteen parameters characterizing the crystal field of rare-earth ions in the RMO perovskites (R = Pr, Nd, M = Ga, Co) are calculated by expanding the local Hamiltonian express…
Effect of Ising-type Tb ions on the low-temperature magnetism of La, Ca cobaltite
K. Knížek, Z. Jirák, J. Hejtmánek +5
Crystal and magnetic structures of the member of LaTbCaCoO perovskite series have been determined from the powder neutron diffraction. E…
Phase transition in Pr0.5Ca0.5CoO3 and related cobaltites
J. Hejtmanek, Z. Jirak, O. Kaman +5
We present an extensive investigation (magnetic, electric and thermal measurements and X-ray absorption spectroscopy) of the Pr0.5Ca0.5CoO3 and (Pr1-yYy)0.7Ca0.3CoO3 (y=0.0625-0.15…
Properties of the hole and electron doped perovskites LnCoO3
Z. Jirak, J. Hejtmanek, K. Knizek +1
Two extreme members of the cobaltite series, LaCoO3 and DyCoO3, were investigated by the electrical resistivity and thermopower measurements up to 800-1000 K. Special attention was…
