Our goals are to create novel magnetic materials with reduced dimensionality, explore the size- and dimension related phenomena and understand the underlying new physics. Our interests include the structural, electronic and magnetic properties of superlattices, sandwiches, wedges, ultrathin films, wires and quantum dots, and encompass lithographic patterning and self-assembly. The challenge is to identify fundamentally new phenomena associated with the competition between spatial and magnetic length scales and change of dimensionality. We tailor properties via preparation conditions and manipulation of dimensionality for structures grown via molecular beam epitaxy (MBE), sputtering, and novel patterning and templating strategies. We utilize the spin polarized scanning tunneling microscopy (SP-STM), magneto-optical Kerr effect (MOKE), Vibrating Sample Magnetometry (VSM) and operate magneto-transport facilities. We study basic fabrication, magnetic microstructures, magneto-transport, and magneto-optical phenomena. The new phenomena explored extend our basic understanding of low dimensional magnetism and lay the foundations for emergent technologies.
