文摘
- •
We successfully deposited amorphous silicon thin films co-doped with Mn and B.
- •
Structural, electronic, and magnetic properties have been carefully characterized.
- •
A ferromagnetic behavior up to room temperature was detected.
- •
The extrinsic origin of magnetism is excluded.
- •
Boron can play a relevant role to avoid quenching of magnetic moment in Mn ions.
