2D Ruddlesden-Popper Phase Hydride Double Perovskite A4NiVH8 (A = Na, K, Rb): Ferromagnetic Semiconductors With High Curie Temperatures.

2D ferromagnetic semiconductors are recognized as the cornerstone of next-generation spintronics devices. However, their practical applications are severely hindered by the low Curie temperature, which originates from the weak d-p-d ferromagnetic sup…
