Abstract

The antiferromagnetic-to-ferromagnetic phase transition in FeRh films induced by heating with a femtosecond laser pulse was investigated using the time-resolved magneto-optical Kerr effect. An initial rise time of the magneto-optical signal of about 500 fs is found as the FeRh is heated through the transition. The data offer a complementary view to previous pump-probe experiments on "simple" ...
