Electron spin filtering in ferromagnet/semiconductor heterostructures
(2003)Circularly polarized light was used to generate spin-polarized electrons at room temperature in ferromagnet (FM)/GaAs Schottky diode structures. A change in the helicity-dependent photocurrent was obtained when the ...

Spin-gap and antiferromagnetic correlations in low-dimensional PbNi2-xAxV2O8 compounds (A = Mg, Co)
(2002)The effect of the impurity doping in the quantum-spin chains of the PbNi2V2O8 Haldane-gap compound is studied. We report elastic neutron scattering and bulk magnetic susceptibility measurements on the quasi-one-dimensional ...
