Our standard deposition and characterization tools comprise DC-RF Sputtering, Photolithography, VSM, AFM, XRD, and RAMAN spectroscopy, all facilitated by the central analytical laboratory at BITS-Pilani, Hyderabad Campus. We employ advanced methodologies, including Magneto-Optical Kerr Effect (MOKE), Faraday Effect Spectroscopy, and current-induced spin-Hall measurement, to study spintronic heterostructures and the effect of interfaces. Furthermore, we execute micro-magnetic device and circuit-level simulations using UBERMAG and PySPICE.
MOKE
We use both longitudinal and polar MOKE to study magnetism in thin films and 2D materials. A LED is being used to illuminate the sample surface to view micron sized flakes
Laser
Currently we have two continuous diode lasers. One red laser (632 nm) of 50mW power, and one green laser (532 nm) 20mW power.
RF and DC Sputtering
This is a central facility, we we regualrly use to deposite our thin films.
Lock-in-amplifier
This lock-in amplifier in the MOKE setup captures tiny signals. This is referenced using a mechanical chopper in the incoming laser path.
Digital Multimeter
This digital multimeter is used to measure small currents.

Faraday Rotation
This is a shared facility with Prof. Kannan Ramaswamy. We use this instrument to study iron absorption in protein cages
Workstation
This one is being mainly used by Sneha to study micromagnetic simulations of current-induced domain wall motion.
Microscope Objectives
We have a few long-working distance microscope objectives, which we switch according to our requirements.
Electromagnet
We have an electromagnet coupled with a power supply and a chiller. It can produce with ~1.2 T magnetic field.
