Abstract

Magnetic properties of a patterned micro-NiFe element were analyzed with micro-MOKE and micromagnetics. Patterned 8 μm × 16 μm NiFe elements have higher coercive field, H_c = 1.9 Oe, for the hard axis than that, H_c = 0.2 Oe, of a 5 mm diameter disk NiFe sample. The magnetization reversal processes have been investigated with the micromagnetic simulation for the various applied field directions. The increase of coercive field in patterned micro-NiFe elements can be attributed to the large shape anisotropy and pinned spins along the edges. Total anisotropy of a 8 μm × 16 μm NiFe sample was about 50 Oe. The magnetization reversal field of pinned spins along the edges in patterned micro-NiFe sample was about 500 Oe.
