| dc.description.abstract-en | A Co2FeSi (CFS) film with L21 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 ≈6 × 1015 ion cm−2, while they decrease with
further increasing fluences and finally vanish at a fluence of
≈9 × 1016 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 × 1014 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 caused by a reduction of
the exchange interaction within the film material. | en |
