Search Faculty Profile

Dr. Harinath Aireddy received his doctoral degree in Instrumentation & Device Fabrication from IIT Kharagpur, and his M.Tech. degree in Composite Materials from NIT Rourkela. He is an Assistant Professor and active scientist in the Department of Electronics and Communication Engineering.

He has specialized in Instrumentation (design, fabrication, testing, data acquisition, automation and computer control with LabVIEW, calibration and demonstration), spintronics and advanced materials. Through a serious of investigations, he has developed Cantilever Beam Magnetometer (CBM) for electric field induced magnetic measurements, which is the first of its kind in the world. He has also developed an ultra-low-vibration Liquid Nitrogen (LN2) flow cryostat (which is inexpensive, has reduced vibration and fantastic variable temperature) for low temperature measurements in optical cantilever beam magnetometer set-up, which is also the first of its kind in the world. Further, Dr. Aireddy also developed a double cantilever beam set-up for simultaneous magnetostriction measurements of two different or same type of samples for sensor/actuator applications.  He has also been one of the researchers in the world to fabricate and investigate semiconductor-based spin diodes and spin transistors for MRAM and MFRAM applications.
