Areas of Expertise

  • Experimental synthesis, magnetism, and structural characterization of intermetallic compounds containing rare-earth elements
  • Magnetocaloric effect and its applications
  • Relationships between composition, structure, physical and chemical properties of materials exhibiting extraordinary responses to external stimuli (temperature, pressure, magnetic field)
  • Polymorphic solid state phase transformations; coupled magnetic and structural transformations leading to giant magnetocaloric effect, magnetostriction, and magnetoresistance

Research

Research Interests

  • Rare-earth intermetallic compounds, their synthesis and crystallography, composition-structure-property relationships, and physical behaviors.
  • Discontinuous anhysteretic phase transitions, in situ powder X-ray diffraction, and characterization of magnetic and thermal properties.
  • Magnetism and associated functionalities, including magnetocaloric effect, magnetostriction, magnetoresistance, and hard magnetic properties.
