WebMagnetoresistance measurements are done on control devices to ensure spin dependency of the observed effect. Magnetoresistance of the FM/NM/NM lateral devices are found to be negligible (∼0.02%) confirming that the magnetoresistance in FM/NM/FM devices is due to the spin-valve effect only. WebTunnel magnetoresistance ( TMR) is a magnetoresistive effect that occurs in a magnetic tunnel junction ( MTJ ), which is a component consisting of two ferromagnets separated by a thin insulator. If the insulating layer is thin enough (typically a few nanometres ), electrons can tunnel from one ferromagnet into the other.
