Abstract

Antiferromagnetic interlayer exchange coupling in semiconductor EuS--PbS--EuS ferromagnetic trilayers grown on PbS (001) substrates with ultrathin (0.6--1.2nm) nonmagnetic PbS spacers is studied by SQUID magnetometry and model calculations. Analysis of the experimentally observed magnetic field and temperature dependence of the magnetization of EuS--PbS structures reveals a rapid decrease in the interlayer coupling energy with increasing temperature indicating a temperature dependence of the microscopic coupling mechanism acting in these all-semiconductor ferromagnetic/ nonmagnetic multilayers.
