Abstract
We report our experimental investigation on the temperature-dependent hysteresis loops and magnetic domain
behaviors of CoFeB (0.4 nm)/Pd (1 nm) multilayer on polyimide substrate with a perpendicular magnetic
anisotropy, by means of magneto-optical Kerr microscopy. Hysteresis characteristics such as saturation magnetization,
coercivity, and hysteresis loop area with respect to the temperature have been analyzed, where powerlaw
scaling behaviors are observed with microscopic magnetic domain patterns mediated by numerous nucleation
sites.
