Facilities<\/h2>\n\n\n\n\n\n\n

Solid state synthesis<\/h3>\n\n\n\n\nMaterials for thin film targets are synthesized using high temperature box furnace and tube furnaces (with provision for oxygen rich atmosphere for heating)\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Epitaxial thin film growth<\/h3>\n\n\n\n\n

<\/span><\/span><\/strong>      <\/span><\/span><\/span><\/strong>The thin film growths are performed using a\npulsed laser deposition system, the heart of it being a KrF excimer laser. An\nin-situ Reflection High Energy Electron Diffraction system (RHEED) is installed\nto monitor layer by layer growth. <\/span><\/span><\/span><\/p>\n\n

Transport measurements<\/h3>\n\n\n\n\n

A number of setups are present in the lab to carry out extensive transport measurements<\/p>\n\nA closed cycle cryostat operating on Gifford McMahon refrigeration cycle, to measure electrical transport from 300 K to 4 K temperature.\nLiquid Nitrogen dipstick setups to measure electrical transport from 300 K to 77 K.\nA superconducting magnet running on liquid Helium that can measure upto 2 K temperature and ramp magnetic field from -9 to 9 Tesla. Both in-plane and out of plane magnetic field for magneto-transport measurements are feasible.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Department Central facilities<\/h3>\n\n\n\n\n

Several department central facilities are used.<\/span>
<\/p>\n\nRigaku based X-ray diffraction facility using Cu K-\u221d rays to carry out thin film and powder X-ray diffraction and X ray-reflectivity for film characterization.\nAtomic Force Microscopy to characterize surface properties of the thin film.\nMPMS for magnetic measurements.\nWire bonder for bonding purpose.\n\n\n\n\n\n\n\n\n\n\n

Large scale facilities<\/h3>\n\n\n\n\nWe also perform various x-ray based experiments and muon spin rotation spectroscopy at synchrotron and muon sources around the globe.
