Claim Text:
1. A magnetic multilayer film for a temperature sensor comprising: a bottom magnetic composite layer disposed on a substrate, the bottom magnetic composite layer having a direct pinning structure, an indirect pinning structure, a synthetic ferromagnetic structure, or a synthetic anti-ferromagnetic structure; a spacer layer disposed on the bottom magnetic composite layer; and a top magnetic composite layer disposed on the spacer layer, the top magnetic composite layer having the direct pinning structure, the indirect pinning structure, the synthetic ferromagnetic structure, or the synthetic anti-ferromagnetic structure, wherein a ferromagnetic layer of the bottom magnetic composite layer closest to the spacer layer has a magnetic moment anti-parallel with that of a ferromagnetic layer of the top magnetic composite layer closest to the spacer layer.
