Mechanochemistry in spin-glass mosaic perovskites
ORAL
Abstract
Mixed-metal halide perovskites have been reported to exhibit emergent electronic properties including strong optical absorption and pressure-dependent electronic conductivity in Cu(I)-Cu(II)-In(III) chloride perovskites in a p-chloroanilinium matrix [1]. Inspired by these phenomena and the success of a solvent-free mechanochemical synthesis route, a new family of mosaic perovskites is studied for its emergent magnetic properties. These materials have been synthesized using ball-milling and solution-based techniques. The mechanochemical driving force behind its atomistic clustering, short-range ordering, and spin-glass character is analyzed based on advanced Ising and Hubbard models [2,3]. These 2D halide perovskites in an organic matrix represent a general design strategy in materials design of magnetic properties via mechanochemical alloying.
