Magnetic and thermodynamic properties of RMnO (R = Pr, Nd)
J. Hemberger, M. Brando, R. Wehn +4
The ground state properties of the pure perovskite compounds PrMnO and NdMnO were investigated by magnetization, magnetic AC susceptibility and specific heat measurements.…
Complex interplay of 3d and 4f magnetism in La:GdMnO3
J. Hemberger, S. Lobina, H. -A. Krug von Nidda +5
We report on structural, magnetic, electrical, and thermodynamic properties of Gd-doped LaMnO3 single crystals for Gd doping levels 0 <= x <= 1. At room temperature, for all doping…
Dielectric behavior of Copper Tantalum Oxide
B. Renner, P. Lunkenheimer, M. Schetter +3
A thorough investigation of the dielectric properties of Cu2Ta4O12, a material crystallizing in a pseudo-cubic, perovskite-derived structure is presented. We measured the dielectri…
Large and Small Polaron Excitations in La2/3(Sr/Ca)1/3MnO3 Films
Ch. Hartinger, F. Mayr, J. Deisenhofer +2
We present detailed optical measurements of the mid-infrared (MIR) excitations in thin films of La2/3Sr1/3MnO3 (LSMO) and La2/3Ca1/3MnO3 (LCMO) across the magnetic transition. The…
Dielectric properties and dynamical conductivity of LaTiO3: From dc to optical frequencies
P. Lunkenheimer, T. Rudolf, J. Hemberger +4
We provide a complete and detailed characterization of the temperature-dependent response to ac electrical fields of LaTiO3, a Mott-Hubbard insulator close to the metal-insulator t…
Doping dependence of the gap anisotropy in LCCO studied by millimeter-wave spectroscopy
A. V. Pronin, A. Pimenov, A. Loidl +2
We measure the penetration depth of optimally doped and underdoped La2-xCexCuO4 in the millimeter frequency domain (4 - 7 cm-1) and for temperatures 2 K < T < 300 K. The penetratio…
The Orbital Order Parameter in La0.95Sr0.05MnO3 probed by Electron Spin Resonance
J. Deisenhofer, B. I. Kochelaev, E. Shilova +3
The temperature dependence of the electron-spin resonance linewidth in La0.95Sr0.05MnO3 has been determined and analyzed in the paramagnetic regime across the orbital ordering tran…
Evidence for Jahn-Teller distortions at the antiferromagnetic transition in LaTiO
J. Hemberger, H. -A. Krug von Nidda, V. Fritsch +8
LaTiO is known as Mott-insulator which orders antiferromagnetically at K. We report on results of thermal expansion and temperature dependent x-ray diffraction…
