Spin-lattice coupling in the ferrimagnetic semiconductor FeCr2S4 probed by surface acoustic waves
C. Mueller, V. Zestrea, V. Tsurkan +3
Using surface acoustic waves, the elastomagnetic coupling could be studied in thin single crystalline plates of the ferrimagnetic semiconductor FeCr2S4 by measuring the attenuation…
Microcanonical Ensemble Extensive Thermodynamics of Tsallis Statistics
A. S. Parvan
The microscopic foundation of the generalized equilibrium statistical mechanics based on the Tsallis entropy is given by using the Gibbs idea of statistical ensembles of the classi…
Toroid Current States in Doped Mott Insulators
Dmitry I. Iudin, Alexander P. Protogenov
The free energy bounds for inhomogeneous current states in doped antiferromagnetic insulators and spatial configurations of spin and charge degrees of freedom in lightly and heavil…
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…
