Dr. Sanjay Mishra, professor of physics at the University of Memphis, has received
a National Science Foundation-Division of Civil, Mechanical and Manufacturing Innovation
Grant for research on permanent magnets.The $298,481 award is for “Grain Refined Nanocomposites:
A Study on the Effect of Additives on Microstructure and Magnetic Properties of Permanent
Dr. Sanjay Mishra
A permanent magnet is a piece of magnetic material which, once magnetized by an external
magnetic field, must retain a large magnetic moment after the magnetizing force is
removed. Permanent magnets have wide industrial applications, from motors and generators
to space equipment. The project will investigate a promising new technology for the
production of high-energy product permanent magnets for power-dense machines. In order
to minimize their carbon footprint, new generation of permanent magnets must be small
and lightweight,but have a high energy density and operating temperature.
The U of M study will focus on the fundamental understanding of the interplay between
structure and magnetic properties of the permanent magnet that will ultimately help
in designing lightweight, power-dense, high-temperature permanent magnets.
The study will provide excellent learning opportunities for graduate and undergraduate
students and strengthen the Materials Science concentration in the Department of Physics.
The award also will improve the departmental equipment infrastructure, aiding other
interdisciplinary research activities throughout the campus.
“Clearly, the proposed research will form the basis for developing technologically
important materials for the benefit of society,” said Mishra.
