Proximity-tuned Magnetic and Transport Anomalies in All-epitaxial Fe5-xGeTe2/WSe2 Van der Waals Heterostructures
Researchers created high-quality Fe5−xGeTe2/WSe2 heterostructures to study emergent 2D physics and spintronics. They found perpendicular magnetic anisotropy and room-temperature ferromagnetism, revealing complex magnetic transitions linked to different iron sublattices. The interplay between bulk and interfacial effects dictates unconventional transport anomalies like the Hall effect.
