Single-ion anisotropy in the gadolinium pyrochlores studied by an electron paramagnetic resonance
V. N. Glazkov, M. E. Zhitomirsky, A. I. Smirnov +4
The electron paramagnetic resonance is used to measure the single-ion anisotropy of Gd3+ ions in the pyrochlore structure of (Y{1-x}Gdx)2Ti2O7. A rather strong easy-plane type anis…
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…
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…
Terahertz Conductivity at the Verwey Transition in Magnetite
A. Pimenov, S. Tachos, T. Rudolf +5
The complex conductivity at the (Verwey) metal-insulator transition in Fe_3O_4 has been investigated at THz and infrared frequencies. In the insulating state, both the dynamic cond…
Glassy Aging Dynamics
P. Lunkenheimer, R. Wehn, U. Schneider +1
We present time-dependent dielectric loss data at different frequencies for a variety of glass formers after cooling below the glass temperature. The observed aging dynamics is des…
