Research Group

Major Research Facilities:

• DC and AC magnetometry facilities using Quantum Design Physical Properties Measurement System (PPMS) with 6T magnet and in-field transport accessory.
• Pulsed Laser Deposition System with Nd-YAG laser operating from 1024 to 266nm.
• Atomic Force Microscope (AFM) with magnetic force microscopy (MFM) and conductive force microscopy options.
• Spectrophotometer for reflectance and transmission studies in the UV/Vis/NIR.
• X-ray Diffractometer for powder pattern studies.
• Closed cycle He system for low field DC and AC magnetizations and ferroelectric studies.
• Solid state reaction, chemical route preparation and spin coating facilities.

CURRENT RESEARCH ACTIVITIES:

• The research activities of the Magnetic Nanostructures group are focused on the development, characterization and studies of nanostructures such as nanoparticles, thin films and nanocomposites.
• We are currently studying the effects of finite size, surface effects and interparticle separations on the magnetic, semiconducting and multiferroic properties.
• Exchange bias, half metallicity, phase separation and coexistence of ferroelectric and ferromagnetic behavior and band gap variations with size are some of our current research themes.
• Atomic and magnetic force microscopy is being used to determine physical parameters at the nanoscale.
