摘要: Abstract The magnetization reversal of the magnetically soft permalloy ( Fe 20 Ni 80 ) layer in a spin-valve-like FeNi/Cu/Co trilayer was studied using photoelectron emission microscopy combined with X-ray magnetic circular dichroism, which allows to image domain structure an element-selective way. Nanosecond-short field pulses amplitudes between 3.3 and 16.3 mT were applied one by reverse FeNi layer. Images taken after application each pulse, mobility wall motion deduced. mechanism found depend on pulse length, amplitude, energy direction coupling two ferromagnetic layers.
