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…
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…
The ground state properties of the mixed-valence cobaltites NdSrCoO, NdCaCoO and PrCaCoO
Z. Jirak, J. Hejtmanek, K. Knizek +5
The electric, magnetic, and thermal properties of three perovskite cobaltites with the same 30% hole doping and ferromagnetic ground state were investigated down to very low temper…
Magnetodielectric effect and optic soft mode behaviour in quantum paraelectric EuTiO3 ceramics
S. Kamba, D. Nuzhnyy, P. Vanek +7
Infrared reflectivity and time-domain terahertz transmission spectra of EuTiO3 ceramics revealed a polar optic phonon at 6 - 300K, whose softening is fully responsible for the rece…
Anomalous magnetoresistance of EuBC: Enhancement of magnetoresistance in systems with magnetic polarons
M. Batkova, I. Batko, K. Flachbart +8
We present results of measurements of electrical, magnetic and thermal properties of EuBC. The observed anomalously large negative magnetoresistance as above, so…
