摘要：Provided are a magnetic transducer and a thin film magnetic head having goodthermal stability and capable of obtaining a high exchange coupling magnetic field, amethod of manufacturing a magnetic transducer and a method of a manufacturing a thinfilm magnetic head. An MR element has a stack having a stacked structure comprising anunderlayer, a crystal-growth inhibitor layer, a first soft magnetic layer, a second softmagnetic layer, a nonmagnetic layer, a ferromagnetic layer, an antiferromagnetic layerand a cap layer, which are stacked in sequence. The ferromagnetic layer has an innerferromagnetic layer, a coupling layer and an outer ferromagnetic layer, which are stackedin this order on the nonmagnetic layer. The crystal-growth inhibitor layer inhibits crystalgrowth of the layers formed on the crystal-growth inhibitor layer, thereby limiting anaverage in-surface particle diameter of the inner ferromagnetic layer to within the rangeof from 3 nm to 8 nm inclusive, so that an interface between the coupling layer and theinner ferromagnetic layer becomes flattened.
