Diluted magnetic semiconductors, or semimagnetic semiconductors,
seemed for a while to be one of those research topics whose glory
(i. e. , the period of most ext- sive research) belongedalready to
the past. This particularlyapplied to "traditional" diluted
magnetic semiconductors, i. e. , substitutional alloys of either
II-VI or IV-VI semiconductors with transition metal ions.
Fortunately, a discovery, in the beg- ning of the nineties [1,2],
of ferromagnetic ordering in III-V DMSs with critical temperatures
reaching 170 K has renewed and greatly intensi ed an interest in
those materials. This was, at least partially, related to
expectations that their Curie temperatures can be relatively easily
brought to room temperature range through a clearly delineatedpath
and,partially,due to the great successes, also commercial,of
metallic version of spintronics, which earned its founders the
Nobel Prize in 2007. The semiconductor version of spintronics has
attracted researchers also because of hopes to engage it in efforts
to construct quantum information processing devices. While these
hopes and expectations are not fully realized yet, the effort is
going on. As a goodexampleof recentachievements,new resultson
quantumdotsconta- ing a single magnetic ion should be mentioned. A
great progress has been achieved in studies of excitonic states in
such quantum dots, so far limited to InAs/GaAs [3,4] and CdTe/ZnTe
[5,6] material systems and to Manganese as the magnetic ion.
Furthermore, in the II-VI QDs, rst results on the optical control
of the Mn spin states
havebeenexperimentallydemonstrated[7-9]andtheoreticallyanalyzed[10];
the studies of Mn spin dynamics and control in III-V QDs will
certainly follow.
