Multiferroic behavior in CdCr2X4 (X = S, Se)
J. Hemberger, P. Lunkenheimer, R. Fichtl +3
The recently discovered multiferroic material CdCr2S4 shows a coexistence of ferromagnetism and relaxor ferroelectricity together with a colossal magnetocapacitive effect. The comp…
Relaxation dynamics and colossal magnetocapacitive effect in CdCr2S4
P. Lunkenheimer, R. Fichtl, J. Hemberger +2
A thorough investigation of the relaxational dynamics in the recently discovered multiferroic CdCr2S4 showing a colossal magnetocapacitive effect has been performed. Broadband diel…
Charge-Density-Wave like Behavior in the One-Dimensional Charge-Ordered Semiconductor (NbSe4)3I
D. Staresinic, P. Lunkenheimer, J. Hemberger +2
We report on broadband dielectric spectroscopy on the one-dimensional semiconductor (NbSe4)3I. Below the structural phase transition close to 270 K we observe colossal dielectric c…

We report on the new compound UCuSn which crystallizes in the tetragonal structure \emph{I}4/\emph{mcm} with lattice parameters and …
Glassy freezing of orbital dynamics in FeCr2S4 and FeSc2S4
R. Fichtl, P. Lunkenheimer, J. Hemberger +2
We report on a thorough dielectric investigation of the glass-like freezing of the orbital reorientation-dynamics, recently found for the crystalline sulpho-spinels FeCr2S4 and FeS…
Relaxor ferroelectricity and colossal magnetocapacitive coupling in ferromagnetic CdCr2S4
J. Hemberger, P. Lunkenheimer, R. Fichtl +3
Multiferroic materials, which reveal magnetic and electric order, are in the focus of recent solid state research. Especially the simultaneous occurrence of ferroelectricity and fe…
Heat capacity of the quantum magnet TiOCl
J. Hemberger, M. Hoinkis, M. Klemm +4
Measurements of the heat capacity C(T,H) of the one-dimensional quantum magnet TiOCl are presented for temperatures 2K < T < 300K and magnetic fields up to 5T. Distinct anomalies a…
Observation of a Griffiths phase in paramagnetic La1-xSrxMnO3
J. Deisenhofer, D. Braak, H. -A. Krug von Nidda +8
We report on the discovery of a novel triangular phase regime in the system La1-xSrxMnO3 by means of electron spin resonance and magnetic susceptibility measurements. This phase is…
