STRAINED TUNED STRUCTURES AND FUNCTIONS IN MIXED ANION COMPOUNDS

Abstract:
Mixed-anion compounds are attracting attention because of novel functions that are not found in oxides [1]. In this presentation, I show several examples where strain can alter structures and properties of mixed-anion compounds. The first example is anion-vacancy ordered perovskite SrV(O,N)3-x thin film, in which the period and orientation of anion-deficient layers can be altered by biaxial strain from a substrate [2]. In EuVO2H films, substrate strain induces electron transfer from Eu2+ to V3+, resulting in a 4-fold enhancement of the ferromagnetic transition temperature and perpendicular magnetic anisotropy [3]. In addition, in a series of layered oxychalcogenides synthesized at high pressure, the giant tensile strain provided during decompression process from the chalcogen layer can add new functions to the oxide layer [4-5].
