Spontaneous Strain-Spin Transition Coupling Molecular Crystal with Thermal Magnetic Memory Effect, Anisotropic High-κ and Switchable Dielectric Permittivity. [PDF]

open access: yesAdv Sci (Weinh)
A radical salt undergoes a paraelastic‐ferroelastic phase transition, which is coupled with spin‐Peierls transition, resulting in it integrating self‐strain, spin bistability, switchable dielectric and high‐ properties. Abstract Materials that exhibit controllable changes in electrical, magnetic, or spontaneous strain properties, particularly those ...

Controlling internal barrier in low loss BaTiO3 supercapacitors [PDF]

open access: yes, 2009
Supercapacitor behavior has been reported in a number of oxides including reduced BaTiO3 ferroelectric ceramics. These so-called giant properties are however not easily controlled. We show here that the continuous coating of individual BaTiO3 grains by a

Linking hopping conductivity to giant dielectric permittivity in oxides [PDF]

open access: yes, 2010
With the promise of electronics breakthrough, giant dielectric permittivity materials are under deep investigations. In most of the oxides where such behavior was observed, charged defects at interfaces are quoted for such giant behavior to occur but the
