Electron‐mediated ferromagnetism persisting to room temperature has been investigated in epitaxial (Ga,Mn)N films with low Mn concentration grown by plasma‐enhanced molecular beam epitaxy (PEMBE).The experimental value of T C (∼325 K) in the (Ga,Mn)N film with x = 0.3% from the difference (Δ M ) between field‐cooled (FC) and zero field‐cooled (ZFC) magnetization curves is found to be lower than the estimated value of T C (∼407 K), obtained by the mean field approximations. The extra‐ordinary Hall effect in the epitaxial (Ga,Mn)N film with x = 0.2% is found to appear in the temperature range 100 K–300 K. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
