Abstract

We observe all-optical switching (AOS) in ferrimagnetic Fe100−x Tb x alloy films below, above, and in samples without a magnetic compensation point. AOS is linked to a low remanent magnetization M R and associated with laser heating up to the Curie temperature. Above M R = 220 emu/cc AOS is replaced by pure thermal demagnetization.
