Group Leader : Dr. Shrawan Mishra

We highly encourage application for PhD position. JRF/DST Inspire Fellowship holders can directly contact the Group Leader (shrawan.mst@iitbhu.ac.in).
 

The quantum materials research group is highly interested in various levels of general characterization and measurement techniques like x-ray and neutron scattering and spectroscopy, magneto-transport, magnetization measurements, magnetic imaging, and laser spectroscopy. In a series of projects, we focus on the study of high-quality thin films multilayers, and single crystals as our study materials. Some of these systems are patterned at the micrometre and sub-micrometre scale using lithographic methods.  In the second series of projects,  the group concentrates on exploring the reduced dimensions, and the spatial confinement gives rise to modified or new physical properties in various nanostructures grown by self-assembly. These confined systems include magnetic nanoparticles, metallic nanoclusters and biomolecular assemblies. Below are the few thrust topics that we are interested in:

• Magnetic Materials and Confined Magnetism
• Magnetic Imaging and Magnetospectroscopy
• X-ray and Neutron Diffraction /Scattering Techniques
• Energy Efficient Quantum Materials and Phase Change Materials
• Mulfiferroics and Magneto-optical Materials
• Smart Materials and Sensors
• Spin Related Phenomena at Low Temperatures
• Charge, Lattice, and Spin Dynamics 
• Magnetic Memory and Spintronic devices

•  Sample growth by solid-state reactions, and thin film depositions like magnetron sputtering & PLD.
•  X-ray diffraction, other structural characterization methods like AFM, and TEM.
•  Conventional magnetometry like SQUID, vibrating sample magnetometer (VSM), magneto-optical Kerr effect (MOKE), and imaging  techniques.
•  Soft X-rays based absorption spectroscopy, resonant scattering, element specific magnetic imaging, and coherent X-rays based speckle metrology.  
• Neutron Diffraction and Small Angle Scattering.
