Magnetic adatoms on two-dimensional NbSe2

摘要: In the last decade, much research has been focused on quasi-two-dimensional magnetism in monolayers or buried interfaces [1]. Two-dimensional transition metal dichalcogenides are very interesting from a fundamental point of view, as magnetism and charge-density waves compete with each other. Magnetic impurities may modify a charge-density wave, by altering its energetic stability as well as its local patterns. The charge density wave in turn affects how magnetic impurities can interact with each other, modulating the exchange coupling. Therefore, inducing magnetism with external chemical species has the potential to be an effective way to engineer new electronic and magnetic phases in perspective of technological applications. In this poster, we present our study on the extrinsic magnetism arising from adsorbed transition metals on two-dimensional NbSe2 [2, 3]. We demonstate that each investigated …
