Zusammenfassung:	An apparatus is configured to include a first magnetic layer, a second magnetic layer and a break layer between the first magnetic layer and the second magnetic layer. The first magnetic layer includes a Curie temperature gradient between a first surface and a second surface of the first magnetic layer. The second magnetic layer includes a Curie temperature gradient between a third surface and a fourth surface of the second magnetic layer. The first magnetic layer has an average Curie temperature that is higher than the second magnetic layer.
