摘要：

A relationship between initial ferromagnetic magnetostatic coupling strength (HF) and a long-term thermal stability of the spin valve (SV) sensors was investigated. The thermal degradation in GMR properties of SV stacks is more apparent in the stack exhibiting a higher initial HF, and is expedited for the stacks without capping layers. Initial HF values appear to be one of the good indicators for the long-term thermal stability of SV stacks since they reflect the inter-layer microstructure of SV sensor stacks. The origin of HF is also discussed by comparing measured HF values with estimated ones.
