What Does TMR Stand For?
TMR stands for Tunneling Magnetoresistance
Tunneling Magnetoresistance (TMR) is a quantum mechanical phenomenon observed in magnetic devices, where the resistance of a material changes in response to an external magnetic field. This effect occurs in structures composed of two ferromagnetic layers separated by a thin insulating barrier. When the magnetic orientations of the layers are parallel, the resistance is lower compared to when they are antiparallel. TMR is crucial in spintronics and has significant applications in magnetic sensors and data storage technologies, offering enhanced performance and energy efficiency.
