recommendations! Published in 2022 at "Advanced Materials"

DOI: 10.1002/adma.202208221

Abstract: Interfacial magnetism stimulates the discovery of giant magnetoresistance (MR) and spin–orbital coupling across the heterointerfaces, facilitating the intimate correlation between spin transport and complex magnetic structures. Over decades, functional heterointerfaces composed of nitrides have seldom… read more here.
