The Quench sample exhibited a tweed pattern, suggesting the coexistence of two phases at the nanometer scale. The nanostructural changes from a fine twin structure to a checkerboard nanostructure, followed by the emergence of a lamellar-type nanostructure, were clearly observed as the cooling rate decreased from quenching to 1 °C h−1. It was suggested that the diffusion of manganese ions accompanied by the Jahn–Teller distortion play an important role in the formation of nanostructures of this system.}, pages = {105002-1--105002-5}, title = {Control of nanostructures by cooling rate in spinel-type manganese oxide ZnMnGaO4}, volume = {59}, year = {2020}, yomi = {ホリベ, ヨウイチ} }
