PURPOSE: A magnetoresistive thin film with superior thermal characteristics for a top or bottom type spin valve and a method for manufacturing the same are provided to prevent the diffusion of elements generated in respective layers by forming a proper oxide layer in the laminate structure and the transmission of Mn generated in an antiferromagnetic layer to other layers, thereby improving the thermal characteristics. CONSTITUTION: A magnetoresistive thin film with superior thermal characteristics for a top type spin valve is in the laminate structure of a buffer layer, a first ferromagnetic layer, a nonmagnetic layer, a second ferromagnetic layer, an oxide layer, another second ferromagnetic layer, an antiferromagnetic layer, and a protecting layer stacked on a substrate in sequence. The structure is formed by deposition in the DC magnetron sputtering and the oxide layer is introduced in the process of the deposition.
