Tunnel devices come into the light

Murata has launched its first series of high-performance coreless current sensors using tunnel magneto-resistive (TMR) elements (writes Nick Flaherty). The MRD series of open-loop current sensors integrates high-performance TMR elements. These use a magneto-resistive effect that occurs in a magnetic tunnel junction composed of two ferromagnets separated by a thin insulator. The insulator, typically a […]
