Orbital Freezing in FeCr2S4 Studied by Dielectric Spectroscopy
R. Fichtl, P. Lunkenheimer, J. Hemberger +2
Broadband dielectric spectroscopy has been performed on single-crystalline FeCr2S4 revealing a transition into a low-temperature orbital glass phase and on polycrystalline FeCr2S4…
Field-controlled phase separation at the impurity-induced magnetic ordering in the spin-Peierls magnet CuGeO3
V. N. Glazkov, A. I. Smirnov, H. -A. Krug von Nidda +3
The fraction of the paramagnetic phase surviving at the impurity-induced antiferromagnetic order transition of the doped spin-Peierls magnet Cu(1-x)Mg(x)GeO3 (x < 5%) is found to i…
Non-intrinsic origin of the Colossal Dielectric Constants in CaCu3Ti4O12
P. Lunkenheimer, R. Fichtl, S. G. Ebbinghaus +1
The dielectric properties of CaCu3Ti4O12, a material showing colossal values of the dielectric constant, were investigated in a broad temperature and frequency range extending up t…
Spin and orbital frustration in MnSc_2S_4 and FeSc_2S_4
V. Fritsch, J. Hemberger, N. Buettgen +4
Crystal structure, magnetic susceptibility, and specific heat were measured in the normal cubic spinel compounds MnSc_2S_4 and FeSc_2S_4. Down to the lowest temperatures, both comp…
Spin fluctuations in the quasi-two dimensional Heisenberg ferromagnet GdI_2 studied by Electron Spin Resonance
J. Deisenhofer, H. -A. Krug von Nidda, A. Loidl +3
The spin dynamics of GdI_2 have been investigated by ESR spectroscopy. The temperature dependences of the resonance field and ESR intensity are well described by the model for the…
