Spin-driven Phase Transitions in ZnCrSe and ZnCrS Probed by High Resolution Synchrotron X-ray and Neutron Powder Diffraction
F. Yokaichiya, A. Krimmel, V. Tsurkan +7
The crystal and magnetic structures of the spinel compounds ZnCrS and ZnCrSe were investigated by high resolution powder synchrotron and neutron diffraction. ZnCr$_…
Colossal magnetocapacitive effect in differently synthesized and doped CdCr2S4
S. Krohns, F. Schrettle, P. Lunkenheimer +2
In the present work, we address the question of an impurity-related origin of the colossal magnetocapacitive effect in the spinel system CdCr2S4. We demonstrate that a strong varia…
Self-similarity degree of deformed statistical ensembles
A. I. Olemskoi, A. S. Vaylenko, I. A. Shuda
We consider self-similar statistical ensembles with the phase space whose volume is invariant under the deformation that squeezes (expands) the coordinate and expands (squeezes) th…
High-pressure x-ray diffraction study on the structure and phase transitions of the defect-stannite ZnGa2Se4 and defect-chalcopyrite CdGa2S4
D. Errandonea, R. S. Kumar, F. J. Manjon +2
X-ray diffraction measurements on the sphalerite-derivatives ZnGa2Se4 and CdGa2S4 have been performed upon compression up to 23 GPa in a diamond-anvil cell. ZnGa2Se4 exhibits a def…
Search for Gravitational Wave Bursts from Soft Gamma Repeaters
LIGO Scientific Collaboration, S. Barthelmy, N. Gehrels +2
We present the results of a LIGO search for short-duration gravitational waves (GWs) associated with Soft Gamma Repeater (SGR) bursts. This is the first search sensitive to neutron…
Specificity of Phase Transition of Quasi-Spin System in Two-Quantum Exchange with Thermostat
Nicolae Enaki, Vitalie Eremeev
The quantum phase transition of the system of N radiators in case of two-photon exchange interaction with cavity electromagnetic field is considered. It is shown that for this syst…
