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…
Absence of commensurate ordering at the polarization flop transition in multiferroic DyMnO3
J. Strempfer, B. Bohnenbuck, M. Mostovoy +6
Ferroelectric spiral magnets DyMnO3 and TbMnO3 show similar behavior of electric polarization in applied magnetic fields. Studies of the field dependence of lattice modulations on…
Anomalous thermal expansion and strong damping of the thermal conductivity of NdMnO and TbMnO due to 4f crystal-field excitations
K. Berggold, J. Baier, D. Meier +6
We present measurements of the thermal conductivity and the thermal expansion of NdMnO and TbMnO. In both compounds a splitting of the multiplet of the $R^{3+}…
Evidence for local lattice distortions in giant magnetocapacitive CdCr2S4
V. Gnezdilov, P. Lemmens, Yu. G. Pashkevich +6
Raman scattering experiments on CdCr2S4 single crystals show pronounced anomalies in intensity and frequency of optical phonon modes with an onset temperature T*=130 K that coincid…
REPLY to Comments on "Giant Dielectric Response in the One-Dimensional Charge-Ordered Semiconductor (NbSe4)3I" and "Colossal Magnetocapacitance and Colossal Magnetoresistance in HgCr2S4" (cond-mat/0607500)
P. Lunkenheimer, J. Hemberger, V. Tsurkan +3
In the present work we reply to the Comment by Catalan and Scott (cond-mat/0607500) on two of our papers. This Comment has been rejected from publication in Physical Review Letters…
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…
