ABSTRACT:
A magnetic thin film includes magnetic crystal grains and a region where an average crystal size of the magnetic crystal grains along a first direction is smaller than an average crystal size of the magnetic crystal grains along a second direction that is orthogonal to the first direction. Magnetization along the first direction is effected by an external magnetic field that is smaller than an external magnetic field for magnetization along the second direction. Thus, excellent characteristics in a high frequency can be obtained.
