Examines the structural and magnetic ordering of a series of Fe[sub3]O[sub4]/NiO superlattices grown by molecular beam epitaxy, using SQUID magnetometry and both x-ray and neutron diffraction techniques. Comparison between the symmetry of Fe[sub3]O[sub4] spinel and NiO rocksalt structures; Details of the crystal growth and characterization of Fe[sub3]O[sub4] and NiO thin films; Influence of superlattice layering on the Verwey transition manifested in the iron oxide layers.

    We report on an enhancement of the Curie temperature in GaMnAs/InGaMnAs superlattices grown by low-temperature molecular beam epitaxy which is due to thin InGaMnAs or InGaAs films embedded into the GaMnAs layers. The pronounced increase of the Curie temperature is strongly correlated to the In...
