A facility for the preparation and characterization of magnetic thin films with large magneto-optic effects. These materials are used as digital data storage media, light modulators, and magnetic sensors. Thin film deposition equipment consists of an UHV metal MBE, a three source electron beam evaporator, and a high rate magnetron sputtering system. The wavelength dependance of the magneto-optic effects can be studied in fields up to 5 Tesla in the temperature range of 2 to 300 K using a special optical dewar. Other characterization equipment includes a vibrating sample magnetometer, and inductive hysteresis loop tracer, and Hall effect and magneto-resistance loop tracers.

Current Research Projects:

• The preparation of films containing two magnetic phases which are exchange coupled antiferromagnetically (macroscopic ferrimagnets).
• Giant magnetoresistance of granular metals which consist of magnetic metal precipitates in a nonmagnetic metal matrix.
• Epitaxial growth of magnetic intermetallic compounds.
• Magnetic anisotropy of amorphous alloys.
