ABSTRACT:
A high frequency magnetic property measuring apparatus for soft magnetic film includes a magnetic detection device for detecting the intensity of magnetization in a sample material, a high frequency magnetic field generator for generating magnetic field, a power source for supplying current to the magnetic field generator, and a data processing device for getting high frequency magnetic parameters of the sample by using a detection signal output from the magnetic detector. The magnetic field generator is made up of a plane-shaped coil of a conductor having a configuration in which both ends of the plane-shaped coil are closed to form a cavity as a second internal cavity in which the detector is placed. The magnetic detector is made up of a plane-shaped coil of a conductor having a configuration in which both ends of said plane-shaped coil are closed to form a cavity as a first internal cavity in which the sample material is placed. The magnetic detector is placed in the magnetic field generator.
