Controlled aggregation of magnetic ions in a semiconductor. Experimental demonstration
A. Bonanni, A. Navarro-Quezada, Tian Li +8
The control on the distribution of magnetic ions into a semiconducting host is crucial for the functionality of magnetically doped semiconductors. Through a structural analysis at…

Experimental probing of exchange interactions between localized spins in the dilute magnetic insulator (Ga,Mn)N
A. Bonanni, M. Sawicki, T. Devillers +16
The sign, magnitude, and range of the exchange couplings between pairs of Mn ions is determined for (Ga,Mn)N and (Ga,Mn)N:Si with x < 3%. The samples have been grown by metalorgani…

Observation of strong-coupling effects in a diluted magnetic semiconductor (Ga,Fe)N
W. Pacuski, P. Kossacki, D. Ferrand +8
A direct observation of the giant Zeeman splitting of the free excitons in (Ga,Fe)N is reported. The magnetooptical and magnetization data imply the ferromagnetic sign and a reduce…
