Abstract(in English) | The soft magnetic properties of NiFe/FeCo/NiFe sandwich films with high saturation magnetization are discussed in relation to the microstructure. Ta/NiFe/FeCo/NiFe/Ta films prepared using the UHV sputtering process show a very sharp fiber texture of bcc-<110> in the FeCo layer. It was revealed that thin NiFe film with a thickness of only 3 nm works effectively as a seed layer of FeCo film to control the microstructure, resulting in a significant reduction of the coercivity. The best thickness of the FeCo layer in order to realize both soft magnetic properties and high saturation magnetization was found to be ~100nm. It was fond that [FeCo/NiFe]_4 single pole head using bulk coil showed better overwrite performance than that of CoZrNb head. |
