Upper bound for the s-d exchange integral in n-(Ga,Mn)N:Si from magnetotransport studies
R. Adhikari, W. Stefanowicz, B. Faina +3
A series of recent magnetooptical studies pointed to contradicting values of the s-d exchange energy N0α in Mn-doped GaAs and GaN as well as in Fe-doped GaN. Here, a strong sensiti…
Experimental determination of Rashba spin-orbit coupling in wurtzite -GaN:Si
W. Stefanowicz, R. Adhikari, T. Andrearczyk +5
Millikelvin magnetotransport studies are carried out on heavily -doped wurtzite GaN:Si films grown on semi-insulating GaN:Mn buffer layers by metal-organic vapor phase epitaxy.…
Manipulating Mn--Mg cation complexes to control the charge- and spin-state of Mn in GaN
Thibaut Devillers, Mauro Rovezzi, Nevill Gonzalez Szwacki +15
Owing to the variety of possible charge and spin states and to the different ways of coupling to the environment, paramagnetic centres in wide band-gap semiconductors and insulator…
Magnetooptical properties of (Ga,Fe)N layers
J. Papierska, J. -G. Rousset, W. Pacuski +13
Magnetooptical properties of (Ga,Mn)N layers containing various concentrations of Fe-rich nanocrystals embedded in paramagnetic (Ga,Fe)N layers are reported. Previous studies of su…
Phase diagram and critical behavior of the random ferromagnet
S. Stefanowicz, G. Kunert, C. Simserides +11
Molecular beam epitaxy has been employed to obtain Ga1-xMnxN films with x up to 10% and Curie temperatures T_C up to 13 K. The magnitudes of T_C and their dependence on x, T_C(x) ~…
Relation between exciton splittings, magnetic circular dichroism, and magnetization in wurtzite (Ga,Fe)N
J. -G. Rousset, J. Papierska, W. Pacuski +12
The question of the correlation between magnetization, band splittings, and magnetic circular dichroism (MCD) in the fundamental gap region of dilute magnetic semiconductors is exa…
