  The high TC ferromagnetism in (Ga,Mn)N were observed and almost all results
are approximately similar to the experimental results in (Ga,Mn)As except the
value of TC. Though all standard experiments on magnetism clearly support the
results, the value is unexpectedly high. This work present and discuss the
possibility of high TC ferromagnetism, after brief review of the experimental
results. The key speculation to Bosonization method in three dimensions is
resembled with the problems in Anderson localization.
