摘要：

The uniaxial magnetic anisotropies by torque measurement have been measured for Fe16N2(001) single crystal films grown by molecular beam epitaxy (MBE). It has been found that Fe16N2(001) films exhibits perpendicular uniaxial anisotropy which makes the easy axis along the [001] direction, and those anisotropy constants K-U1 and K-U1 for Fe16N2 were 1.6 X 10(7) and 0.4 X 10(7) erg/cm(3), respectively. Those K-U1 and K-U2 for Fe16N2 were constant in the thickness range from 34 to 83nm, The ferromagnetic resonance of Fe16N2(001) single crystal films have been measured. The saturation magnetic flux densities, 4 pi M-S for Fe16N2 measured by the magnetic torques and resonance fields agreed well with the values measured with a vibrating sample magnetometer (VSM).
