Dipolar relaxation, conductivity, and polar order in AgCN
P. Lunkenheimer, A. Loidl, G. P. Johari
By using dielectric spectroscopy in a broad range of temperatures and frequencies, we have investigated dipolar relaxations, the dc conductivity, and the possible occurrence of pol…
Thermal expansion and the glass transition
P. Lunkenheimer, A. Loidl, B. Riechers +2
Melting is well understood in terms of the Lindemann criterion, essentially stating that crystalline materials melt when the thermal vibrations of their atoms become such vigorous…
Antipolar transitions in GaNbSe and GaTaSe
M. Winkler, L. Prodan, V. Tsurkan +2
We present dielectric, polarization, resistivity, specific heat, and magnetic susceptibility data on single crystals of the lacunar spinels GaNb4Se8 and GaTa4Se8, tetrahedral clust…
Magnetic avalanche of non-oxide conductive domain walls
Somnath Ghara, Korbinian Geirhos, Lukas Kuerten +4
Atomically sharp domain walls (DWs) in ferroelectrics are considered as an ideal platform to realize easy-to-reconfigure nanoelectronic building blocks, created, manipulated and er…
Optical, dielectric, and magnetoelectric properties of ferroelectric and antiferroelectric lacunar spinels
K. Geirhos, S. Reschke, S. Ghara +3
Lacunar spinels with a chemical formula of form a populous family of narrow-gap semiconductors, which offer a fertile ground to explore correlation and quantum phenomena,…
Lithium-salt-based deep eutectic solvents: Importance of glass formation and rotation-translation coupling for the ionic charge transport
A. Schulz, P. Lunkenheimer, A. Loidl
Lithium-salt-based deep eutectic solvents, where the only cation is Li+, are promising candidates as electrolytes in electrochemical energy-storage devices like batteries. We have…
