摘要: Power losses of laser scribed GO electrical sheets were measured in the frequency range from 0.05 to 500 Hz and subdivided both into static eddy current losses, low high induction losses. High are increased by treatment while a only with very intensity but they reduced if intensities used. Low rise nearly constant. Similarly hysteresis scribing show similar behavior as It can be concluded that power mainly determined increase defects produced scribing, mobility movement rigid domain walls rotation magnetic moments well wall annihilation recreation having minor influence.
