| Popis: | The effects of high-energy electron beam and pulsed excimer laser irradiation on the magnetic properties of Fe80B20 amorphous alloy are investigated by means of transmission and conversion electron Mossbauer spectroscopy (CEMS) and scanning electron microscopy (SEM). Both types of irradiation were found to induce changes in the magnetic anisotropy of Fe80B20, but the influence of high-energy electron beam irradiation was weaker. Depending on the number of applied laser pulses and repetition rate, controlled magnetic anisotropy and/or relaxation of internal stresses could be obtained by excimer laser irradiation. The presence of molten zones subsequently solidified and of laser-induced internal stresses supports the model of closure domain structure. |
