Implication

Experimental analysis reveals concurrent rotation and wall motion during magnetization reversal in nickel-iron thin films, indicating field angle and film thickness dictate switching behavior.

Key Points

Investigate the mechanisms of magnetization reversal in specially prepared uniaxial nickel-iron thin films under alternating magnetic fields.
Fabricated uniaxial thin films composed of nickel-iron alloy with varying thicknesses.
Measured 400 cycles per second (c.p.s.) hysteresis loops under varying magnetic field orientations relative to the anisotropy axis, including fields applied perpendicularly.
Both coherent rotation and domain wall motion occur simultaneously during magnetization reversal within the same film.
The relative contribution of rotation versus wall motion changes depending on film thickness and the angle of the applied field relative to the anisotropy axis.
Identified distinct magnetic response properties when external fields are applied normal to the anisotropy axis.
