Giant and Oscillatory Junction Magnetoresistance via RKKY-like Spin Coupling in Spin-Gapless Mn${}_2$CoAl/SiO${}_2$/p-Si Heterostructures

Nilay Maji, Subham Mohanty, Pujarani Dehuri

Here, we report spin-selective transport and exceptionally large positive junction magnetoresistance (JMR) in sputter-deposited Mn${}_2$CoAl/native-SiO${}_2$/p-Si heterostructures. Hig…
