Anomalous expansion and phonon damping due to the Co spin-state transition in RCoO_3 with R = La, Pr, Nd and Eu
K. Berggold, M. Kriener, P. Becker +4
We present a combined study of the thermal expansion and the thermal conductivity of the perovskite series RCoO_3 with R = La, Nd, Pr and Eu. The well-known spin-state transition i…
Anomalous thermal expansion and strong damping of the thermal conductivity of NdMnO and TbMnO due to 4f crystal-field excitations
K. Berggold, J. Baier, D. Meier +6
We present measurements of the thermal conductivity and the thermal expansion of NdMnO and TbMnO. In both compounds a splitting of the multiplet of the $R^{3+}…
Magnetothermal transport in the spin-1/2 chains of copper pyrazine dinitrate
A. V. Sologubenko, K. Berggold, T. Lorenz +4
We present experiments on the thermal transport in the spin-1/2 chain compound copper pyrazine dinitrate Cu(C_4 H_4 N_2)(NO_3)_2. The heat conductivity shows a surprisingly strong…
Uniaxial pressure dependencies of the phase transitions in GdMnO
J. Baier, D. Meier, K. Berggold +4
GdMnO shows an incommensurate antiferromagnetic order below K, transforms into a canted A-type antiferromagnet below K, and for finite magnetic fields a…
Hysteresis effects in the phase diagram of multiferroic GdMnO
J. Baier, D. Meier, K. Berggold +4
We present high-resolution thermal expansion and magnetostriction measurements of GdMnO, which develops an incommensurate antiferromagnetic order (ICAFM) below…
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…
