Magnetization characteristic of ferromagnetic thin strip by measuring anisotropic magnetoresistance and ferromagnetic resonance

• The magnetization characteristic of ferromagnetic thin strip is obtained through measuring anisotropic magnetoresistance and ferromagnetic resonance in different configurations.
• Indicating how the magnetization vector rotates by changing the intensity of external magnetic field of certain direction.
• Demagnetization and magnetic anisotropy are considered.

The magnetization characteristic in a Permalloy thin strip is investigated by electrically measuring the anisotropic magnetoresistance and ferromagnetic resonance in in-plane and out-of-plane configurations. Our results indicate that the magnetization vector can rotate in the film plane as well as out of the film plane by changing the intensity of external magnetic field of certain direction. The magnetization characteristic can be explained by considering demagnetization and magnetic anisotropy. Our method can be used to obtain the demagnetization factor, saturated magnetic moment and the magnetic anisotropy.
