Sr. Research Scientist
Name: Jagadeesh S. Moodera
Title(s): Sr. Research Scientist
Phone: (617) 253-5423
Massachusetts Institute of Technology
Area of Physics:
Experimental condensed matter physics
Experimental condensed matter physics - fundamental and applied research that includes nanospintronics, spin polarized transport and tunneling, thin film magnetism, superconductivity and topological insulators.
Current research topics:
- Spin filter tunneling and internal exchange field effects.
- Topological insulators – Growth of ultra thin films and spin transport studies (collab. with Profs. P. Jarillo-Herrero and N. Getty).
- In search of Majorana Fermions (Collab with Prof. P. Lee).
- Organic spintronics.
- Spin filtering and transport into graphene (collab with CNRS/Thales/U of Paris, France and EPFL, Switzerland).
- Spin filtering phenomenon in oxides (collab. with CEA, Saclay, France).
- Spin polarized transport/tunneling studies in nanostructures of metals and semiconductors. (Collab. with Korea Institute of Science and Technology, Seoul, Korea)
Other interests include interfacial magnetism and chemical studies in relation to tunneling and transport of spins by polarized neutron reflectivity, X-ray absorption spectroscopy, X-ray magnetic circular dichroism etc (collaboration with scientists from NIST, Brookhaven National Lab, Lawrence Berkeley Lab and Diamond Light Source in UK).
Dr. Jagadeesh S. Moodera received his Ph.D in Physics from Indian Institute of Technology (Madras). He joined MIT in 1981 as a research staff at the Francis Bitter National Magnet Laboratory (FBML), where he currently leads the “Thin Film Magnetism, Superconductivity and Nanospintronics” group. He is a visiting professor at Technological Univ. of Eindhoven (The Netherlands), an adjunct professor at Suffolk University, Distinguished Foreign Scientist at National Physical Laboratory (India) and a Distinguished Professor at IIT (Chennai, India). Dr. Moodera is a Fellow of American Physical Society and has received several national and international awards including Oliver Buckley Prize in Condensed Matter Physics from APS (2009).
Dr. Moodera’s many years of research in the area of spin polarized tunneling led to the breakthrough in observing tunnel magnetoresistance (TMR) at room temperature in magnetic tunnel junctions (1995). This resulted in a huge surge in this area of research, currently one of the most active areas. TMR effect is used in all ultra-high density magnetic data storage since about 2004, as well as for the development of non-volatile magnetic random access memory (MRAM).
The research group over the years has consisted of students at all levels, postdoctorals and visiting scientists. Students include high school honors students during summer, diploma/masters candidates from Europe, undergraduates (UROP) and graduate students.
