Orbital Glass in FeCr2S4
V. Tsurkan, V. Fritsch, J. Hemberger +11
Low-temperature heat-capacity investigations on the spinel FeCr2S4 with ferrimagnetic spin order and orbitally degenerated Jahn-Teller active Fe2+ ions in a tetrahedral crystal fie…
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…
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…
