Planar array of self-assembled GaFeN nanocrystals in GaN: Magnetic anisotropy determined via ferromagnetic resonance
Andreas Grois, Thibaut Devillers, Tian Li +1
The magnetic anisotropy of a planar array of GaFeN nanocrystals (NCs) embedded in a GaN host is studied by ferromagnetic resonance. X-ray diffraction and transmission…
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…
Origin of low-temperature magnetic ordering in Ga1-xMnxN
M. Sawicki, T. Devillers, S. Gałȩski +9
By employing highly sensitive millikelvin SQUID magnetometry, the magnitude of the Curie temperature as a function of the Mn concentration x is determined for thoroughly characteri…
The Fe-Mg interplay and the effect of deposition mode in (Ga,Fe)N doped with Mg
A. Navarro-Quezada, N. Gonzalez Szwacki, W. Stefanowicz +9
The effect of Mg codoping and its deposition mode on the Fe distribution in (Ga,Fe)N layers grown by metalorganic vapor phase epitaxy is investigated. Both homogeneously- and digit…
Effects of s,p - d and s - p exchange interactions probed by exciton magnetospectroscopy in (Ga,Mn)N
J. Suffczynski, A. Grois, W. Pacuski +6
Near band-gap photoluminescence and reflectivity in magnetic field are employed to determine the exchange-induced splitting of free exciton states in paramagnetic wurtzite Ga1-xMnx…
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…
