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…
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…
GaN:-Mg grown by MOVPE: structural properties and their effect on the electronic and optical behaviour
Tian Li, Clemens Simbrunner, Matthias Wegscheider +4
The effect of Mg -doping on the structural, electrical and optical properties of GaN grown $\textsl{via}$ metalorganic vapor phase epitaxy has been studied using transmission el…
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…
Paramagnetic GaN:Fe and ferromagnetic (Ga,Fe)N - relation between structural, electronic, and magnetic properties
A. Bonanni, M. Kiecana, C. Simbrunner +8
We report on the metalorganic chemical vapor deposition (MOCVD) of GaN:Fe and (Ga,Fe)N layers on c-sapphire substrates and their thorough characterization via high-resolution x-ray…
