Research concerns the investigation of the magnetic properties of alloys and their relationship to metallurgical structures and processing variables. Computer-controlled equipment is available for alternating-current magnetic-susceptibility measurements as a function of frequency, temperature, and magnetic field. An automated vibrating sample magnetometer, a high-field (7-T) superconducting quantum interference device magnetometer, a magnetic force microscope, Lorentz microscopy, and a newly developed magneto-optical indicator film apparatus are available; as well as equipment for ferromagnetic resonance, Mössbauer effect, magnetocaloric effect, and magnetoresistance measurements. Interests include magnetic properties of advanced materials including thin magnetic films, compositionally modulated alloys, magnetic multilayers, magnetic nanocomposites, granular metals, high-temperature superconductors, metallic glasses, icosahedral crystals, and others. Time effects and relaxation phenomena are of particular interest. Applications to nondestructive-evaluation techniques, e.g., Barkhausen effect, are also pursued.
