Abstract

The specific heat of II-IV group Fe-based DMS has been investigated at temperatures below 20 K. All zero- and open-gap compounds have a magnetically inactive singlet ground state, well separated from the excited states. Within a crystal field model one is in principle able to understand this behaviour in all cases. The Fe2+-Fe2+ interaction and the role of the Fe levels in the band structure will be discussed.
