- •
Local structural/electronic properties around Mn in Cd1−xMnxTe1−ySey are determined.
- •
Influence of different types of Mn–Te bonds on electronic structure is established.
- •
Mn and Te excess charges are found to be distinctly different from their valences.
- •
The spin-up states are spatially much more extended than the spin-down states.
- •
Small magnetic dipole moment forms at the Mn–Te bond critical points.
