Dr. Pechan's primary area of research is in condensed matter magnetism.
The ongoing developments in, for example, magnetic recording technology
require an understanding of magnetic properies in increasingly smaller
and yet more well defined magnetic domains. The studies of microstructure
electromagnetism, motivated by such progress, provides tremendous potential
for enhancing our understanding of basic magnetic interactions in solids.
Furthermore, condensed matter magnetism has long served as an experimental
and theoretical testing ground for modeling physical phenomenon which are
Current investigatations involve multilayer structures comprised of
alternating materials with dissimilar magnetic properties and nanometer
scale layer thicknesses. For example, the interesting phenomena of coupling
between magnetic layers across nonmagnetic interlayers in Co/Cr and Fe/Cr
systems is probed dynamically with ferromagnetic resonance (FMR) and statically
with vibrating sample magnetometry (VSM). In addition, anisotropy energies
are detemined using FMR, VSM and torque magnetometry. Of particular interest
is the anisotropy contribution arising from the interface between dissimilar
magnetic materials. Magnetic/magnetic systems such as Co/Ni are also yielding
some suprising superlattice effects in both the anisotropy and the the
Dr. Pechan's current pedagogical interests center on laboratory development
at both the introductory and advanced undergraduate levels.
