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…
Colossal dielectric constants in single-crystalline and ceramic CaCu3Ti4O12 investigated by broadband dielectric spectroscopy
S. Krohns, P. Lunkenheimer, S. G. Ebbinghaus +1
In the present work the authors report results of broadband dielectric spectroscopy on various samples of CaCu3Ti4O12, including so far only rarely investigated single crystalline…
Broadband dielectric response of CaCu3Ti4O12: From dc to the electronic transition regime
Ch. Kant, T. Rudolf, F. Mayr +4
We report on phonon properties and electronic transitions in CaCu3Ti4O12, a material which reveals a colossal dielectric constant at room temperature without any ferroelectric tran…
Broadband dielectric spectroscopy on single-crystalline and ceramic CaCu3Ti4O12
S. Krohns, P. Lunkenheimer, S. G. Ebbinghaus +1
We present dielectric measurements of the colossal dielectric constant material CaCu3Ti4O12 extending up to 1.3 GHz also covering so far only rarely investigated single crystalline…
