About:

Dr. Dileep Kumar has been working as a scientist in the UGC-DAE CSR, Indore, since Sept 2008. He earned his Ph.D. from UGC-DAE CSR in 2006 and completed his post-doc at ESRF, France. After joining UGC-DAE CSR, he designed and developed a versatile and unique facility at the center, which allows the characterization of thin films under UHV conditions. In this, thin films can be characterized in-situ during deposition to study magnetic, transport, and structural properties using MOKE, RHEED, and X-ray scattering. He has also designed and developed a UHV-based real-time stress measurement system for studying stress evolution during thin film growth. Apart from this, he has also been involved in several developments. Dr Kumar and his team are actively engaged in keeping the in-situ facility updated and functioning for the users. The unique features of the in-situ set-up are being used by the university and in-house users for their intended experiments. In addition to this, his group is actively involved in the research activity in thin-film nanostructure with a motivation to extend the limit of magnetic anisotropy, tunability in exchange bias, nanopatterning using an ion beam, columnar growth at glancing angle deposition to control shape anisotropy in magnetic thin films and controlling the interface diffusion in organic spin-valve structures. Furthermore, he has recently demonstrated the potential of the x-ray standing wave technique to study interface magnetism in buried thin-film structures, which led to publications in high-impact, reputed international journals. He and his team are currently developing a set-up (funded by DST) that will make our users capable of in-situ x-ray fluorescence and small angle x-ay scattering measurements.
