摘要：
Provided is a method of evaluating properties of ferrite which can continuously measure change in magnetic properties accompanying change in composition of the ferrite merely by preparing one specimen.A composition gradient ferrite thin film constituted of a plurality of composition gradient ferrite layers which are formed by inclining component composition in the horizontal direction is formed on a single crystal substrate having light transmitting property using a thin film forming method, and a magneto-optical effect is continuously measured along the composition gradient direction of the ferrite thin film whereby change in magnetic properties accompanying a change in composition of the ferrite is continuously measured.
