The epitaxial diluted magnetic semiconductor (Ga,Mn)As is a model system for investigating spin and spin-orbit phenomena in magnetic and semiconducting systems. Studies of this compound have led to the elucidation of new functionalities in experimental spintronic devices, including optical and electrical control of the magnetic order, with general applicability to a wide range of material...

Thin films and powder samples of intrinsic and transition metal doped titanium dioxide were investigated by an atomic resolution hyperfine nuclear technique in order to study the relation between defects and ferromagnetism. Complementarily, the crystalline structure, morphology and composition of the samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and...

The Mössbauer collaboration at ISOLDE/CERN applies short lived isotopes for emission Mössbauer spectroscopy (eMS) within material sciences. Mössbauer spectroscopy (MS) gives various detailed information on the probe atoms, through the hyperfine interactions. There are several benefits of eMS in particular we can perform measurements in the extremely dilute regime (~10$^{-4}$ at. %) and make...

Mn-doped GaAs, or (Ga,Mn)As, has become the model system in which to explore the physics of carrier-mediated ferromagnetism in semiconductors and the associated spintronic phenomena [1]. In particular, as the most widely studied dilute magnetic semiconductors (DMS), (Ga,Mn)As is an ideal example of how the magnetic behavior of DMS materials is strongly influenced by the lattice sites occupied...
