Abstract
We observed weak ferromagnetism in Bi2−xMnxTe3 nanocrystals grown in a glass matrix. Magnetization measurements at 5 K showed an increase in the coercive field that was proportional to Manganese concentration. Transmission Electron Microscopy images showed the formation of Bi2−xMnxTe3 nanocrystals with an average size of 5.0 nm. X-ray diffraction measurements revealed the hexagonal structure of the Bi2−xMnxTe3 nanocrystals and confirmed the replacement of Bi3+-ions with Mn2+-ions at different xMn-concentrations. Electron Paramagnetic Resonance of these Mn-doped Bi2Te3 nanocrystals showed six lines associated with the S = 5/2 spin half-filled d-electrons that are characteristic of Mn2+ ions.
