Work area:

• Multifunctional materials
• Single crystal growth and characterization
• Structural, Magnetism, Dielectric and Transport properties
• Magnetic, magnetocaloric, ferroelectric, multiferroic and multifunctional materials
• Strongly correlated electron systems

Research interest:

Our research interest involves multifunctional materials and various types of strongly correlated electron systems with novel magnetic and electrical properties. These systems are interesting for fundamental understanding as well as technological applications. Our works are based on material synthesis and single crystal growth using different methods and then characterizations of structural, magnetic, transport, impedance spectroscopy, dielectric, ferroelectric and magnetocaloric properties experimentally. Efforts are made to explore novel magnetic, electrical and structural properties, their origin, dynamics under electromagnetic field, correlation among structural, magnetic and electrical properties and their evolution with external parameters like temperature, magnetic field and chemical substitution.
