DESCRIPTION:Prof. Ramamoorthy Ramesh\, University of California at Berkele
 y USA\nComplex perovskite oxides exhibit a rich spectrum of functional res
 ponses\, including magnetism\, ferroelectricity\, highly correlated electr
 on behavior\, superconductivity\, etc.   The basic materials physics of 
 such materials provide the ideal playground for interdisciplinary scientif
 ic exploration with an eye towards real applications.  Over the past deca
 de the oxide community has been exploring the science of such materials as
  crystals and in thin film form by creating epitaxial heterostructures and
  nanostructures.  Among the large number of materials systems\, there exi
 sts a small set of materials which exhibit multiple order parameters\; the
 se are known as multiferroics\, particularly\, the coexistence of ferroele
 ctricity and some form of ordered magnetism (typically antiferromagnetism)
 . The scientific community has been able to demonstrate electric field con
 trol of both antiferromagnetism and ferromagnetism at room temperature. Cu
 rrent work is focused on ultralow energy (1 attoJoule/operation) electric 
 field manipulation of magnetism as the backbone for the next generation of
  ultralow power electronics. In this lecture\, I will describe our progres
 s to date on this exciting possibility.  The lecture will conclude with a
  summary of where the future research is going.\n \nReferences:\n1. Magne

 \, Berkeley in 1987.  He returned to Berkeley in 2004 and is currently th
 e Purnendu Chatterjee Chair Professor in Materials Science and Physics. Fr
 om 1989-1995\, at Bellcore\, he initiated research in several key areas of
  oxide electronics\, including ferroelectric nonvolatile memories.  His l
 andmark contributions in ferroelectrics came through the recognition that 
 conducting oxide electrodes are the solution to the problem of polarizatio
 n fatigue\, which for 30 years\, remained an enigma and unsolved problem. 
 In 1994\, in collaboration with S. Jin (Lucent Technologies)\, he initiate
 d research into manganite thin films and they coined the term\, Colossal M
 agnetoresistive (CMR) Oxides. He initiated pioneering research into multif
 erroic oxides at Maryland. At Berkeley\, he continues to pursue key scient
 ific and technological problems in complex multifunctional oxide thin film
 s\, nanostructures and heterostructures. His group demonstrated the existe
 nce of a large ferroelectric polarization in multiferroic BiFeO3 films\, i
 n agreement with first principle predictions\; they also demonstrated elec
 tric field control of antiferromagnetism as well as ferromagnetism\, a cri
 tical step towards the next generation of ultralow power storage and spint
 ronics devices that are completely electric field controlled. He has publi
 shed extensively on the synthesis and materials physics of complex oxide m
 aterials and his work is highly cited (over 65\,000 citations\, H-factor =
 110).  He is a fellow of APS\, AAAS & MRS. He has been recognized with a 
 Humboldt Senior Scientist Prize\, The American Physical Society’s David 
 Adler Lectureship and the James McGroddy Prize\, the TMS Bardeen Prize and
  the IUPAP Magnetism Prize and Neel Medal. In 2014\, he was recognized as 
 a Thomson-Reuters Citation Laureate in Physics for his work on multiferroi
 cs. From December 2010 to August 2012 he served as the Founding Director o
 f the SunShot Initiative at the U.S. Department of Energy\, overseeing and
  coordinating the R&D activities and funding (300M$/year) of the U.S. Sola
 r Program. In 2011\, he was elected to the National Academy of Engineering
