We report that adsorption of monolayers of organic molecules onto the surface of ferromagnetic semiconductor heterostructures produces large, robust changes in their magnetic properties. The heterostructures have half a monolayer of MnAs embedded in

We examine the relationship between the transport and magnetic properties of digital ferromagnetic heterostructure superlattices in which 0.5 monolayer MnAs planes alternate with undoped GaAs spacer layers. The data show that as the thickness t of th

We use high-field magnetotransport to examine the relation between the Hall effects and the longitudinal resistance, ${R}_{xx}$, in digitally doped (Ga,Mn)As structures with hopping transport. The ordinary and anomalous Hall resistances, ${R}_{\mathr

We present experimental studies of the in-plane magnetic anisotropy of ferromagnetic semiconductor superlattices. The samples have half-monolayer MnAs planes that alternate with GaAs spacers of thickness t = 28, 42, and 56 A. For the lowest-t samples

The authors investigate effects of chemisorption of polar organic molecules onto ferromagnetic GaAs∕GaMnAs heterostructures. The chemisorbed heterostructures exhibit striking anisotropic enhancement of the magnetization, while GaAs substrates that
