RESEARCH WORK OF THE CANDIDATE
Ferrites and ferrite thin films can be used as deflection yoke core in television
picture tubes, memory core devices in computers and antenna cores. They are also
widely used in inductors, memory and switching devices, microwave latching devices,
transformers, etc. At microwave frequencies, ferrites are extensively used in a number
of microwave devices such as – isolators, circulators, gyrators and phase shifters.
Magnetic and electric properties of ferrites are having fundamental and
technological and potential applications. Potential applications such as (1) high density
information storage in computers, (2) ferrofluid technology, magnetocaloric
refrigeration, magnetic resonance imaging (MRI) enhancement, magnetic guided drug
delivery, microwave devices and magnetic recording media and magnetic sensors.
Superparmagnetic nanoparticles also have been used in biomedicine and biotechnology as contrast agents in magnetic resonance imaging (MRI) and as drug carriers
for magnetically guided drug delivery.
Nano-wires
and
nano-structural
thin
films
are
having
fundamental,
technological and potential applications such as thermoelectric power conversion, light
weight protective armor for space shuttles-high temperature semiconductor devices in
nuclear engineering Newton absorbers and solid state Newton detectors.
