Title:
RARE EARTH THIN FILM MAGNET AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/104117
Kind Code:
A1
Abstract:
The present invention pertains to a rare earth thin film magnet containing Pr, Fe, and B as essential components, the rare earth thin film magnet being characterized in that a first layer comprising a Pr phase and an α-Fe phase is provided on a substrate, a second layer comprising a Pr-Fe-B phase is provided on the first layer, a third layer comprising an α-Fe phase is provided on the second layer, and a fourth layer comprising a Pr-Fe-B phase and an α-Fe phase is provided on the third layer. The present invention addresses the problem of providing a rare earth thin film magnet having good magnetic properties and a method for manufacturing the same.
