My research interests span a range of topics related to the development and applications of novel magnetic materials and devices at nanoscale dimensions. These include micro- and nanomagnetic materials and devices directly related to the current and future magnetic storage technologies such as disk drive storage, probe storage based on MEMS and MRAM. Among the investigated issues are fabrication and device physics of magnetic probe heads at nanoscale dimensions (the recording heads with dimensions down to few tens of nanometers have been routinely fabricated using focused ion-beam nanofabrication techniques); development and characterization of nanocrystalline materials for advanced recording media applications; micromagnetic behavior of soft magnetic materials; recording properties of nanocrystalline alloy and superlattice-based media materials; recording processes at nanoscale dimensions, etc. Record track densities in excess of 400ktpi (~60nm track width) were demonstrated using above-mentioned nanoprobe recording heads and specially prepare media. The micromagnetic behavior of magnetic nanotubes was for the first time experimentally observed.
