Description
  • Změny výměnné interakce a spin orbitální vazby způsobené iontovým svazkem v Co2FeSi Heuslerově slitině (cs)
  • A Co2FeSi ( CFS) film with L2(1) structure was irradiated with different fluences of 30 keV Ga+ ions. Structural modifications were subsequently studied using the longitudinal ( LMOKE) and quadratic ( QMOKE) magneto-optical Kerr effect. Both the coercivity and the LMOKE amplitude were found to show a similar behaviour upon irradiation: they are nearly constant up to ion fluences of approximate to 6 x 10(15) ion cm(-2), while they decrease with further increasing fluences and finally vanish at a fluence of approximate to 9 x 10(16) ion cm(-2), when the sample becomes paramagnetic. However, contrary to this behaviour, the QMOKE signal nearly vanishes even for the smallest applied fluence of 3 x 10(14) ion cm(-2). We attribute this reduction of the QMOKE signal to an irradiation-induced degeneration of second or higher order spin - orbit coupling, which already happens at small fluences of 30 keV Ga+ ions. On the other hand, the reduction of coercivity and LMOKE signal with high ion fluences is probably
