The discovery of van der Waals (vdW) magnets opened up a new paradigm for condensed matter physics and spintronic technologies. However, the operations of active spintronic devices with vdW magnets are so far limited to cryogenic temperatures, inhibiting its broader practical applications. Here, for the first time, we demonstrate room temperature spin-valve devices using vdW itinerant ferromagnet Fe5GeTe2 in heterostructures with graphene. The tunnel spin polarization of the Fe5GeTe2/graphene…

Patterning-Induced Ferromagnetism of Fe3GeTe2 van der Waals Materials beyond Room Temperature.
A real-space imaging study of itinerant ferromagnet Fe3 GeTe2 and the enhancement of its Curie temperature well above ambient temperature finds that the magnetic long-range order in Fe3GeTe2 is characterized by an unconventional out-of-plane stripe-domain phase.
Gate-tunable room-temperature ferromagnetism in two-dimensional Fe3GeTe2
It is found that the itinerant ferromagnetism persists in Fe3GeTe2 down to the monolayer with an out-of-plane magnetocrystalline anisotropy, which opens up opportunities for potential voltage-controlled magnetoelectronics based on atomically thin van der Waals crystals.
Room-Temperature Spin Hall Effect in Graphene/MoS2 van der Waals Heterostructures.
This work unambiguously demonstrates experimentally the spin Hall effect in graphene induced by MoS2 proximity and for varying temperatures up to room temperature, paving the way toward the combination of spin information transport and spin-to-charge conversion in two-dimensional materials.
Electrical and thermal generation of spin currents by magnetic bilayer graphene
Proximity coupling of bilayer graphene with the 2D interlayer antiferromagnetic CrSBr now enables active generation of spin currents in graphene both electrically and thermally.
Tunneling Spin Valves Based on Fe3GeTe2/hBN/Fe3GeTe2 van der Waals Heterostructures.
Low-temperature anomalous Hall effect measurements show that thin Fe3GeTe2 crystals are metallic ferromagnets with an easy axis perpendicular to the layers and a very sharp magnetization switching at magnetic field values that depends slightly on their geometry, which suggests that the magnetic properties of the surface are representative of those of the bulk, as may be expected for vdW materials.
