Magnetic properties of vanadium selenide epitaxial thin films
Abstract
The discoveries of ferromagnetism in atomically-thin Cr2Ge2Te6 and CrI3 crystals have opened up an opportunity for integration of magnetic 2D materials into van der Waals heterostructures. Moreover, the recent discovery of emergent room-temperature ferromagnetism in monolayer VSe2, which has been known as a paramagnetic metal in its bulk form, should provide an important step toward spintronics applications based on 2D materials, although the existence of ferromagnetism in monolayer VSe2 is still controversial. We have recently found that vanadium selenide epitaxial thin films fabricated by molecular-beam epitaxy (MBE) with our growth recipe exhibit peculiar magnetic properties with clear anomalous Hall effect down to 2D limit. In this presentation, we will show transport properties of our MBE-grown vanadium selenide epitaxial thin films, and discuss possible origins of this emergent ferromagnetism in our samples.
