Switching the Ferroelectric Polarization by External Magnetic Fields in the Spin = 1/2 Chain Cuprate LiCuVO4
F. Schrettle, S. Krohns, P. Lunkenheimer +5
We present a detailed study of complex dielectric constant and ferroelectric polarization in multiferroic LiCuVO4 as function of temperature and external magnetic field. In zero ex…
Polar phonons and spin-phonon coupling in HgCr2S4 and CdCr2S4
T. Rudolf, Ch. Kant, F. Mayr +3
Polar phonons of HgCr2S4 and CdCr2S4 are studied by far-infrared spectroscopy as a function of temperature and external magnetic field. Eigenfrequencies, damping constants, effecti…
Spin-phonon coupling in antiferromagnetic chromium spinels
T. Rudolf, Ch. Kant, F. Mayr +3
The temperature dependence of eigenfrequencies and intensities of the IR active modes has been investigated for the antiferromagnetic chromium spinel compounds CdCr2O4, ZnCr2O4, Zn…
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…
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…
