Research Highlights

  • Heterostructures comprising bilayers of FM and heavy metal HM are of immense significance in spintronics as they allow the realization of various useful phenomena related to the conversion of spin current to charge current. Dr. Indranil Sarkar's group is developing ferromagnet (FM)/ Heavy non-magnetic metal (HM) bilayers for the creation of novel spintronic applications that can act as efficient spin-pumping platforms.  Novel strategies and intrinsic understanding to enhance spin pumping in these heterostructures are being developed. . A magnetization dynamics lab has been developed for these studies.
  • Dr. Indranil Sarkar's group has developed highly ordered crystalline Heusler nanoparticles and demonstrated the heat generation capability of these nanostructures under the application of alternating magnetic fields. This work presents the possibility of using Heusler nanoparticles as a new w material class for magnet-thermal applications. Through these studies, a new physical structure parameter has been developed that can be used to efficiently control the size, chemical, and crystalline order for designing Heusler nanoparticles.

  • Dr. Indranil Sarkar's group has developed a novel method based on the electrodeposition technique to realize highly crystalline thin films of high spin polarization Heusler compounds that are thermodynamically difficult to achieve using the conventional physical vapor deposition method. This novel class of spintronic materials shows a high degree of magneto-optical response comparable to conventional magnetic alloys. This opens up a great opportunity to realize new classes of spintronic platforms.
