Abstract

Co₅₀Ni₅₀/Pt multilayers with perpendicular magnetic anisotropy have been patterned into single and multi domain dots by laser interference lithography and ion beam etching. The samples (typically 1×1 cm²) have been characterized by VSM, polar Kerr Magnetometry, Torque Magnetometry and Magnetic Force Microscopy. The relation between coercivity, anisotropy and dot size is discussed. Also the rotational hysteresis loss of single and multi domain dots is reported.
