Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

The influence of transition element (TE) doping on the magnetotransport properties of (Formula presented) is studied for the entire transition element series ((Formula presented) Fe, Co, Ni, Cu, Zn) for a fixed (5% at Mn sites) dopant concentration. The systematics of different properties such as the metal-insulator transition temperature (Formula presented) the Curie temperature (Formula presented) (Formula presented) and the maximum value of magnetoresistance (MR), with respect to lattice parameter and the ionic radii of dopants, are examined. The important findings include an interesting correlation between the maximum MR, the lattice parameter, and the ionic radii, and some distinct features exhibited by Fe, Cu, and Zn dopants. © 1999 The American Physical Society.
