The magnetic anisotropy and the magnetization reversal process of a nanometer-scale FeNi antidot array system of triangle lattice were investigated at room temperature by means of torque and resonating-sample magnetometries. The magnetic anisotropy of the system has a sixfold rotational symmetry refracting the structural symmetry of the array of holes. The magnetic anisotropy energy between the hard and easy axes is about 3.2 × 104 J / m3.
