Quantum fluctuations in the effective pseudospin-1/2 model for magnetic pyrochlore oxides
effective pseudospin-1/2 model magnetic pyrochlore oxides
2010/11/25
The e ective quantum pseudospin-1=2 model for interacting rare-earth magnetic moments, which
are locally described with atomic doublets, is studied theoretically for magnetic pyrochlore oxides.It is ...
Here we report a new class of material which we have coined as “nonlinear insulators” that exhibit a reversible electric-field-induced metal-insulator transition. We demonstrate this behaviour for an ...
Viscosity and Glass Transition in Amorphous Oxides
Glass Transition solid-state Amorphous Oxides
2009/9/4
An overview is given of amorphous oxide materials viscosity and glass-liquid transition phenomena. The viscosity is a continuous function of temperature, whereas the glass-liquid transition is accompa...
