Perpendicular uniaxial magnetic anisotropy of Fe{sub 16}N{sub 2}(001) single crystal films grown by molecular beam epitaxy
The uniaxial magnetic anisotropies by torque measurement have been measured for Fe{sub 16}N{sub 2}(001) films exhibits perpendicular uniaxial anisotropy which makes the easy axis along the [001] direction, and those anisotropy constants K{sub U1} and K{sub U2} for Fe{sub 16}N{sub 2} were 1.6 x 10{sup 7} and 0.4 x 10{sup 7} erg/cm{sup 3}, respectively. Those K{sub U1} and K{sub U2} for Fe{sub 16}N{sub 2} were constant in the thickness range from 34 to 83 nm. The ferromagnetic resonance of Fe{sub 16}N{sub 2}(001) single crystal films have been measured. The saturation magnetic flux densities, 4{pi}M{sub s} for Fe{sub 16}N{sub 2} measured by the magnetic torques and resonance fields agreed well with the values measured with a vibrating sample magnetometer (VSM).
