Magnetic field induced phases in anisotropic triangular antiferromagnets: application to
Shi-Zeng Lin, Kipton Barros, Eundeok Mun +6
We introduce a minimal spin model for describing the magnetic properties of . Our Monte Carlo simulations of this model reveal a rich magnetic field induced phase…
Magnetic heat transport in RCuO (R = La, Pr, Nd, Sm, Eu, and Gd)
K. Berggold, T. Lorenz, J. Baier +8
We have studied the thermal conductivity on single crystalline samples of the antiferromagnetic monolayer cuprates RCuO with R = La, Pr, Nd, Sm, Eu, and Gd. For a heat…
Low temperature mixed spin state of Co3+ in LaCoO3 evidenced from Jahn-Teller lattice distortions
V. Gnezdilov, K. -Y. Choi, Yu. Pashkevich +6
One- and multi-phonon excitations of the single crystalline LaCoO3 were studied using Raman spectroscopy in the temperature region of 5 K - 300 K. First-order Raman spectra show a…
Magnetic excitations in the geometric frustrated multiferroic CuCrO
M. Frontzek, J. T. Haraldsen, A. Podlesnyak +9
In this paper detailed neutron scattering measurements of the magnetic excitation spectrum of CuCrO in the ordered state below K are presented. The spectra a…
Thermal conductivity of R2CuO4, with R = La, Pr and Gd
K. Berggold, T. Lorenz, J. Baier +4
We present measurements of the in-plane kappa_ab and out-of-plane kappa_c thermal conductivity of Pr2CuO4 and Gd2CuO4 single crystals. The anisotropy gives strong evidence for a la…
Decoupled spin dynamics in the rare-earth orthoferrite YbFeO: Evolution of magnetic excitations through the spin-reorientation transition
S. E. Nikitin, L. S. Wu, A. S. Sefat +12
In this paper we present a comprehensive study of magnetic dynamics in the rare-earth orthoferrite YbFeO at temperatures below and above the spin-reorientation (SR) transition…
