Abstract
A magnetic thin film laminated structure includes a first layer structure and a second layer structure stacked on the first layer structure. The first layer structure includes an adhesive layer on a substance, the adhesive layer being made of a material having compressive stress, at least one pair of layers on the adhesive layer, each pair of the at least one pair of layers including a magnetic film layer and an isolation layer, and an additional magnetic film layer on the at least one pair of layers. The second layer structure includes another adhesive layer on the first layer structure, another at least one pair of layers on the another adhesive layer, each pair of the another at least one pair of layers including a magnetic film layer and an isolation layer, and another additional magnetic film layer on the another at least one pair of layers.
