Board of Governors Professor
Rutgers, the State University of New Jersey
Martha Greenblatt is Board of Governors Professor of Chemistry in the Department of Chemistry and Chemical Biology, Rutgers University, Piscataway, New Jersey. She received her B.Sc. from Brooklyn College in Chemistry in 1962 and her Ph.D. in Inorganic Chemistry, in 1967 from the Polytechnic Institute, Brooklyn, NY. Greenblatt’s research is focused on solid state inorganic chemistry; synthesis and crystal growth of novel transition metal compounds with quasi-low-dimensional, correlated electronic properties. Another area of research pursued by her was fast ionic (H+, Li+ and O2-) motion in solids, both in crystalline and amorphous materials for applications in solid-state batteries, fuel cells and sensors. She has ~ 500 publications in refereed journals. Her contributions have been recognized by the Francis P. Garvan-John M. Olin Medal 2003, sponsored by Francis P. Garvan-John M. Olin Medal Endowment-National Award by the American Chemical Society for major contribution to the field by a woman chemist. She was Editor-in-Chief of the Materials Research Bulletin, 2000 - 2014. She is on the Editorial Board of several materials journals: Journal of Solid State Chemistry, Member of the Editorial Advisory Board 1989-present; Chemistry of Materials, Advisory Board, 1991-1997; Materials Research Bulletin, Editorial Advisory Board, 1995-2000; Materials Science and Engineering B-solid state materials for advanced engineering, Associate Editor, 1991-1997; Inorganic Chemistry, Member of the Editorial Board, 1993-1996.
Polar and magnetic oxides are fundamentally and technically important, but difficult to prepare. Recently, we were able to synthesize, at high pressure and temperature (HPT) in a Walker-type multi-anvil cell, a number of new compounds, A2BB’O6 in the corundum-derived and perovskite structure with unusually small A-site cations. At HPT the crystal structures of these A2BB'O6 phases allow the incorporation of strong magnetic transition metal ions on all cation sites for magnetic and potentially multiferroic, or magnetoelectric behavior and applications in spintronics. Our aim was to design room-temperature polar ferri- or ferro-magnets by composition modulation of A2BB'O6 phases. So far, we have successfully prepared a series of polar and magnetic oxides, which are LiNbO3-type (R3c) Mn2FeMO6 (M = Nb, Ta) and Zn2FeTaO6; Ni3TeO6-type (R3) ferrimagnetic semiconductor Mn2FeMoO6 and Mn2FeWO6; and half-metallic Mn2FeReO6. We systematically investigated the relationship between the crystal, magnetic, and electronic structure and physical properties.
