  • Development of Ultrathin films and Multilayers for Application in Magnetic Recording Industry, Micro-nano-fabrication
  • Magneto-optical Microscopy

Research Summary

Dr. Jaivardhan Sinha’s current research interest is in the field of spintronics and nanomagnetism with a particular attention on investigating spin dynamics in ferromagnetic thin film heterostructures. For these studies, ultra high vacuum sputter deposition technique has been used to develop thin film heterostructures and micro-nano-fabrication in clean room for various devices fabrication. Brillouin light scattering (BLS) and time resolved magneto-optical Kerr effect (TRMOKE) have been dedicatedly used for optical investigation of magnetization dynamics. Furthermore, high frequency probe-station and various magnetometers have been used to thoroughly characterize the samples and obtain in-depth insight into the fundamental physics.

Highlights of Research

  • In-depth investigation of spin orbit coupling induced effects, particularly, interfacial Dzyaloshinskii-Moriya interaction and spin Hall effect in ferromagnetic thin film heterostructures
  • Development of perpendicularly magnetized ferromagnetic thin film heterostructures and nanofabrication of magnonic crystal
  • Microwave emission from Heusler alloy based spin torque nano-oscillators
