Researchers at the have developed a new experimental technique to measure heating effects in spintronic devices, enhancing our understanding of how heat influences magnetic behavior.
This discovery could pave the way for selecting materials that maintain high functionality with minimal heating, thereby optimizing spintronics for energy efficiency and speed.
Spintronics – devices that use microscopic magnetism in conjunction with electric current – could lead to computing technology as fast as conventional electronics but much more energy efficient. As such devices are developed and studied, an important unresolved question is how device operation is affected by heating.
A new experimental technique, reported by researchers at the University of Illinois Urbana-Champaign in the journal APL Materials, directly measures heating in spintronic devices, allowing direct comparison to other effects. The researchers say that this technique can be used to select spintronic materials whose magnetic behavior is minimally impacted by heating, leading to faster devices.
