The semiconducting character and the large spin moment of 7/2 μB of europium sulfite are important preconditions for applications in the field of spintronics. However, the low Curie temperature (TC=16.5 K) excludes EuS from commercial application. We have studied a variety of Co/EuS multilayer samples deposited in a molecular beam epitaxy system with varying numbers of layers and different single-layer thickness. Magneto-optic Kerr effect measurements at low temperatures (10 K) indicate an antiferromagnetic coupling between EuS and Co moments. © 2004 American Institute of Physics.
