Research Interests  My research concerns the physics of novel magnetic, semiconducting, and superconducting materials. Thin film growth techniques are used to prepare materials not available by bulk preparation techniques, such as amorphous alloys, multilayers, or metastable materials. Current research includes: effects of spin on transport and tunneling, including studies of amorphous magnetically-doped semiconductors and spin injection from ferromagnets into Si; finite size effects on magnetic and thermodynamic properties; formation of perpendicular magnetic anisotropy in films and effects of vapor-deposition growth on short and long range chemical and structural order in amorphous and crystalline alloys. We have an extensive effort in development of calorimetry for thin films and small bulk samples, based on Si-microfabrication techniques.
