To possess the magnetization recording layer which is initialization manner, and reluctance

摘要

Disclosed is a method for initializing a magnetoresistive element which comprises a magnetization recording layer that is a ferromagnetic layer. The magnetization recording layer comprises a magnetization reversal region having a reversible magnetization, a first magnetization fixed region connected to a first boundary of the magnetization reversal region, and a second magnetization fixed region connected to a second boundary of the magnetization reversal region. The method for initializing a magnetoresistive element comprises: a step wherein the magnetizations of the magnetization reversal region, the first magnetization fixed region and the second magnetization fixed region are directed to a first direction; and a step wherein a first magnetic field having a component in a second direction that is opposite to the first direction is applied to the magnetization recording layer, while passing a current between the first magnetization fixed region and the second magnetization fixed region through the magnetization reversal region.
