This review compiles results of experimental and theoretical studies on thin films and
quantum structures of semiconductors with randomly distributed Mn ions, which exhibit …

Spintronics refers commonly to phenomena in which the spin of electrons in a solid state
environment plays the determining role. In a more narrow sense spintronics is an emerging …

Charge carrier holes provide a remarkable system for spintronics and quantum information
technology. In this review paper, I discuss spin-related phenomena in three-dimensional …

Spin injection and detection in silicon is a difficult problem, in part because the weak spin-
orbit coupling and indirect gap preclude using standard optical techniques. Two ways to …

We present evidence for spin-polarized charge carriers in In 2 O 3 films. Both In 2 O 3 and Cr
doped In 2 O 3 films exhibit room-temperature ferromagnetism after vacuum annealing, with …

The carrier spin polarization of magnetic materials is one of the most critical elements for
current-driven spintronics devices. Experimental evidence of spin polarization of magnetic …

We discuss aspects of Andreev reflection (AR) measurements in normal metal-
superconductor (NS) and ferromagnet-superconductor (FS) devices. We describe the …

We show that very large negative magnetoresistance can be obtained in magnetic trilayers
in a current-in-plane geometry owing to the existence of crossed Andreev reflection. This …

We have performed point-contact spectroscopy measurements on a sample constituted by a
metallic ferromagnetic oxide (SrRuO 3) bottom electrode and a tunnel ferrimagnetic (CoFe 2 …

We investigate the spin polarization of the ferromagnetic semiconductor (Ga, Mn) As by point-
contact Andreev reflection spectroscopy. The conductance spectra are analyzed using a …
