Research interests:

My research involves understanding and tailoring solid-state phase transformations in a variety of technologically relevant magneto-functional materials, using processing variables such as temperature, mechanical stress, and magnetic field. These materials are under consideration for either next-generation, highly efficient energy-related devices, or novel biomedical applications.

  1. Tailoring devitrification of Fe-based metallic glasses using thermodynamic variables

Soft ferromagnetic amorphous alloys with Fe(Co)SiB based compositions are considered as testbeds to understand solid-state phase transformations with the application of temperature, magnetic and/or strain field, or appropriate combinations thereof. The Nanomagnetism group disclosed annealing apparatus – Multi-Driver furnace – is an ideal tool to perform specialized annealing with applied stress and/or magnetic field. This research may provide insights into future materials processing to produce product materials with desired structures and properties through the control of the phase transformation using the proposed methodology.

  1. Tuning and evaluating magnetocaloric effect in select magnetocaloric compounds

Magnetocaloric effect (MCE), referring to the adiabatic temperature change of the working materials upon exposure to a varying magnetic field, is the underlying mechanism of magnetic refrigeration, an emerging energy-efficient, environmentally-friendly cooling technology. Here, the operating stabilities of magnetocaloric compounds for long-term refrigeration services were considered, to assess their magnetocaloric potentials operating under extended magnetic filed cycling immersed in a heat transfer fluid.

Experimental and analytic Techniques:

  • Materials processing: Arc melting, Melt spinning, Heat treatments
  • Characterization: X-ray Diffraction (XRD), Magnetometry (VSM, SQUID), Differential Scanning Calorimetry (DSC), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS), Atomic/Magnetic Force Microscopy (AFM/MFM)
  • Software: GSAS-II for Rietveld Refinement of XRD patterns, JADE for XRD analysis, VESTA for crystallographic modeling, ANSYS for electromagnetic simulation, OriginLab, Matlab
