The exchange bias (EB) effect is known as a fundamentally and technologically important magnetic property of a magnetic bilayer film. It is manifested as a horizontal shift in a magnetic hysteresis loop of a film subject to cooling in the presence of a magnetic field. The EB effect in van der Waals (vdW) heterostructures offers a novel approach for tuning the magnetic properties of the newly discovered single-layer magnets, as well as adds a new impetus to magnetic vdW heterostructures. Indeed…

Exchange Bias in Weakly Interlayer-Coupled van der Waals Magnet Fe3GeTe2.

TLDR
The exchange bias effect is examined, a magnetic phenomenon emerging at the ferromagnetic-antiferromagnetic interface, and a possible mechanism for this behavior is proposed, based on the weak interlayer magnetic coupling inherent to vdW magnets, demonstrating the distinct properties of these materials.

Exchange bias and spin–orbit torque in the Fe3GeTe2-based heterostructures prepared by vacuum exfoliation approach

Magnetic two-dimensional (2D) van der Waals (vdWs) materials are receiving increased attention due to their exceptional properties and potential applications in spintronic devices. Because exchange

Proximity effect of a two-dimensional van der Waals magnet Fe3GeTe2 on nickel films.

TLDR
Ferromagnetic resonance measurements show that FGT can increase the perpendicular magnetic anisotropy (PMA) and magnetic damping of the adjacent Ni film and imply its universality in a variety of 2D magnetic materials.

Exchange bias in van der Waals CrCl3/Fe3GeTe2 heterostructures.

TLDR
This work reports exchange-bias fields of over 50 mT in mechanically exfoliated CrCl3/Fe3GeTe2 heterostructures at 2.5 K, the value of which is highly tunable by the field-cooling process and the heterostructure thickness.

Van der Waals engineering of ferromagnetic semiconductor heterostructures for spin and valleytronics

TLDR
The photoluminescence detection of valley pseudospin provides a simple and sensitive method to probe the intriguing domain dynamics in the ultrathin magnet, as well as the rich spin interactions within the heterostructure.

Layer-resolved magnetic proximity effect in van der Waals heterostructures

TLDR
A layer-resolved magnetic proximity effect in heterostructures formed by monolayer WSe 2 and bi/trilayer CrI 3 is reported and a way to control proximity effects and probe interfacial magnetic order via van der Waals engineering is revealed.

TLDR
The MnBi2Te4/CrI3 heterostructure provides a promising platform to realize the electrically tunable zero-field QAH effect by stabilizing surface magnetism, and the high-Chern number QAH state can be achieved by controlling external electric gates.

Gate-tunable room-temperature ferromagnetism in two-dimensional Fe3GeTe2

TLDR
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.

Strong room-temperature ferromagnetism in VSe2 monolayers on van der Waals substrates

TLDR
Reducing the dimensionality of paramagnetic V Se2 results in the emergence of ferromagnetism that is observed in a monolayer and up to room temperature, making VSe2 an attractive material for van der Waals spintronics applications.

Discovery of intrinsic ferromagnetism in two-dimensional van der Waals crystals

TLDR
It is concluded that Cr2Ge2Te6 is a nearly ideal two-dimensional Heisenberg ferromagnet and so will be useful for studying fundamental spin behaviours, opening the door to exploring new applications such as ultra-compact spintronics.
