Abstract
Zn1−xMnxTe dilute magnetic nanocrystals (NCs) were synthesized by fusion method in a glass template and annealed post-growth. Magnetism and quantum confinement of incorporated Mn-ions were confirmed by magnetic force microscopy (MFM), Raman scattering (RS) and electron paramagnetic resonance (EPR). A blueshift in the RS spectra were clear signatures of Mn2+ incorporation in the dot structure which were monitored as a function of increasing doping concentration, x. MFM images strongly indicated the formation of Zn1−xMnxTe magnetic phases in the glass system. The EPR spectra showed six lines associated to the S = 5/2 spin half filled d-state, characteristic of Mn2+ ions.
