Abstract

Heterostructured ABA thin films consisting of two different Prussian blue analogues, where A is a ferromagnet and B is a photoinducible ferrimagnet, have been fabricated for the first time. This novel arrangement allows the magnetization to be decreased by irradiation with white light and significantly increases the ordering temperature of the photoinduced magnetism from 18 to 75 K.

摘要

首次制备了由两种不同普鲁士蓝类似物组成的异质结构 ABA 薄膜，其中 A 是铁磁体，B 是光致顺磁体。这种新颖的排列方式可以通过照射白光来降低磁化强度，并将光致磁有序温度从 18 K 显著提高到 75 K。
