Multiferroics and Magnetics

Calibration of permanent Magnet

  • Calibration of AC/DC Gaussmeter
  • Calibration of Magnetic field indicator
  • Calibration of low field magnetometer
  • Calibration of Helmholtz Coil
  • Calibration of Fluxmeter
  • Calibration of Turn area of search coil
  • Testing of AC/DC electromagnet
  • Power loss measurement of Electrical Steel
  • Magnetic Radiation Measurement

This activity is responsible for maintaining and upgrading National Standard related to magnetic parameter like Magnetic flux Density, Magnetic flux, turn area of search coil, power loss measurement of electrical steel, through continuous development and providing calibration/test facilities of such parameters to industries and institutions as per ISO/IEC: 17025 guidelines which are traceable internationally. We are also trying continuously our best possible efforts to improve further uncertainty of measurement so that we can provide best calibration/test results with minimum error. Our group provides solution to industrial problems also industrial consultancy.

The second major activity of our group is actively involved in world class research on Nano magnetic materials, multiferroic materials, Spintronic, Spin Hall Effect, Dilute Magnetic Semiconductors, SFMO-CMR materials and development of humidity sensor.
