'''Jagadeesh Subbaiah Moodera''' is an [[United States|American]] [[physics|physicist]] of [[India]]n origin and is senior research scientist at [[MIT]]'s [[Francis Bitter]] Magnet Laboratory. In 1994 together with the MIT research team led by P.M. Tedrow and R. Meservey, they showed a practical way to implement room temperature [[magnetic tunnel junction]] (MTJ) using a magnetic stack based on CoFe–Al2O3–Co, demonstrating a [[tunnel magnetoresistance]] ratio (TMR) of 11.8%.

Low temperature magnetoresistive tunneling had been discovered by [[Michel Julliere]] in 1975 but it would be more than a decade before a room temperature system was found. In 1991, [[Terunobu Miyazaki]] and others at [[Tohoku University]] had demonstrated a MTJ with room temperature TMR of 2.7%. In 1994, Miyazaki's team developed a room temperature MTJ with high TMR (18.0%) based on an Fe–Al2O3–Fe stack. Thus, both Miyazaki and Merservey are recognized as the developer of room temperature MTJ.[http://www.research.ibm.com/journal/rd/501/gallagher.html] Besides its great fundamental interest, room temperature magnetoresistive tunnelling is the basis for practical devices including [[MRAM]] and read heads used in [[hard disk]]s.

Moodera was named a Fellow of the [[American Physical Society]] in 2000 "for pioneering and sustained contributions to the understanding of [[spin (physics)|spin]]-polarized transport in solids."{{Citation needed|date=February 2021}} Before investigating ferromagnetic tunneling, Moodera worked on spin-polarized [[quantum tunneling|tunneling]] in superconductor junctions along with [[Bob Meservey]] and [[Paul Tedrow]]. Moodera, Meservey, Tedrow and Miyazaki shared the 2009 [[Buckley Prize|Oliver E. Buckley Condensed Matter Prize]] "for pioneering work in the field of spin-dependent tunneling and for the application of these phenomena to the field of magnetoelectronics."[http://www.aps.org/programs/honors/prizes/prizerecipient.cfm?name=Jagadeesh%20Moodera&year=2009]

Born in [[Bangalore]], India, Moodera attended [[Mysore University]] (B.S. and M.S.) and the [[Indian Institute of Technology]] (Ph.D.). He was briefly at [[West Virginia University]] before joining the [[Francis Bitter Magnet Laboratory]] staff at MIT in 1981.
