Facilities

Solid state synthesis

Materials for thin film targets are synthesized using high temperature box furnace and tube furnaces (with provision for oxygen rich atmosphere for heating)
facilities-1

Epitaxial thin film growth

      The thin film growths are performed using a pulsed laser deposition system, the heart of it being a KrF excimer laser. An in-situ Reflection High Energy Electron Diffraction system (RHEED) is installed to monitor layer by layer growth.

Transport measurements

A number of setups are present in the lab to carry out extensive transport measurements

  • A closed cycle cryostat operating on Gifford McMahon refrigeration cycle, to measure electrical transport from 300 K to 4 K temperature.
  • Liquid Nitrogen dipstick setups to measure electrical transport from 300 K to 77 K.
  • A 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.

Department Central facilities

Several department central facilities are used.

  • Rigaku based X-ray diffraction facility using Cu K-∝ rays to carry out thin film and powder X-ray diffraction and X ray-reflectivity for film characterization.
  • Atomic Force Microscopy to characterize surface properties of the thin film.
  • MPMS for magnetic measurements.
  • Wire bonder for bonding purpose.

Large scale facilities

We also perform various x-ray based experiments and muon spin rotation spectroscopy at synchrotron and muon sources around the globe.
