In recent years, topological insulators have become one of the hottest topics in physics. These new materials act as both insulators and conductors, with their interior preventing the flow of electrical currents while their edges or surfaces allow t…
Washington, D.C. — Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access me…
A simpler and more reliable manufacturing method has allowed two materials researchers to produce nanoscale magnetic sensors that could increase the storage capacity of hard disk drives by a factor of 1,000. Building on results obtained last summer, the new sensors are up to 100 times more sensitive than any current alternative technology, according to researchers Harsh Deep Chopra, University Buffalo associate professor of mechanical and aerospace engineering, and Susan Hua, director of UB’s Bio-Micro-Electro-Mechanical-Systems Facility and adjunct professor of mechanical and aerospace engineering.
