Magneto-optic Response of the Metallic Antiferromagnet Fe${}_2$As to Ultrafast Temperature Excursions

Kexin Yang, Kisung Kang, Zhu Diao +5

The linear magneto-optical Kerr effect (MOKE) is often used to probe magnetism of ferromagnetic materials, but MOKE cannot be applied to collinear antiferromagnets (AFs) due to the…
