Dear all
what is the new and HOT promising diluted magnetic semiconductor materials, that can have ferromagnetic and semiconductor properties close to room temperature? Wich not very difficult to realize (based on typical crystal growth techniques, availability of source)
My question is directed for research purposes, not necessarily for commercial applications.
Please share your knowledge. Additionally, If you know a good paper for this question, please tell me.
Thank you in advance.
Best regards.

Hi,
Previously, ferromagnetism (FM) mostly reported on transition metals (Fe, Co, Cr, Mn etc) doped II-VI and III-V semiconductor (bulk and nanocrystals).
Now, some articles published on Fe doped CsPbCl3 perovskite nanocrystals ( DOI: 10.1039/c9ra07069a).
Thus, you can try doping with transition metals in perovskite Nanocrystals and I-III-VI ternary QDs.
Dear all,
To get the magnetism in the nonmagnetic host material, I would like to know how much percentage doping we can do. Is there any minimum or maximum doping percentage defined or it is different for different materials?
Ferromagnetic chalcopyrites II-IV-V2 have Tc ~ 310-350 K and a diamond-like crystal structure compatible with Si and III-V semiconductors. Transition metal doping is possible in these materials over the entire range of concentrations from 0 to 100%. Here are two relevant references:
