Tuning the spin polarization in monolayer MoS2 through (Y,Yb) co-doping

Yb-Doped monolayer MoS₂ is ferromagnetic at room temperature, and this ferromagnetic state can be stabilized by Y co-doping.

Effect of Ho dopant on the ferromagnetic characteristics of MoS2 nanocrystals

The as-synthesized Ho-doped MoS₂ nanocrystals show intrinsic room-temperature ferromagnetism and their magnetic moment can be tuned by the doping concentration.

Preparation of Boron Nitride Nanoparticles with Oxygen Doping and a Study of Their Room-Temperature Ferromagnetism

In this work, oxygen-doped boron nitride nanoparticles with room-temperature ferromagnetism have been synthesized by a new, facile, and efficient method. There are no metal magnetic impurities in the nanoparticles analyzed by X-ray photoelectron spectroscopy. The boron nitride nanoparticles exhibit a parabolic shape with increase in the reaction time. The saturation magnetization value reaches a maximum of 0.2975 emu g^-1 at 300 K when the reaction time is 12 h, indicating that the Curie temperature ( T_C) is higher than 300 K. Combined with first-principles calculation, the coupling between B 2p orbital, N 2p orbital, and O 2p orbital in the conduction bands is the main origin of room-temperature ferromagnetism and also proves that the magnetic moment changes according the oxygen-doping content change. Compared with other room temperature ferromagnetic semiconductors, boron nitride nanoparticles have widely potential applications in spintronic devices because of high temperature oxidation resistance and excellent chemical stability.
