The magnetic and magneto-optical properties of FeRh thin films epitaxially deposited onto MgO(1
0
0) substrates by RF sputter-deposition system have been investigated in conjunction with the structure. An intriguing virgin effect has been found in the
M–
T curves of the as-deposited FeRh thin films, which is presumably interpreted in term of a change in structural phase when heating. Also, a (negative) maximum peak of Kerr rotation at around 3.8
eV has been observed when FeRh thin films are in ferromagnetic state. The polar Kerr rotation angle is found to increase at temperatures above 100
°C, which corresponds to the antiferromagnet (AF)–ferromagnet (FM) transition of FeRh thin films.
