Improved-Sensitivity Integral SQUID Magnetometry of (Ga,Mn)N Thin Films in Proximity to Mg-doped GaN
Katarzyna Gas, Gerd Kunert, Piotr Dluzewski +3
Nominally 45 nm GaN:Mg/ 5 nm (Ga,Mn)N / 45 nm GaN:Mg trilayers structures prepared by molecular beam epitaxy on GaN-buffered Al2O3 substrates are investigated to verify whether the…
Impact of substrate temperature on magnetic properties of plasma-assisted molecular beam epitaxy grown (Ga,Mn)N
Katarzyna Gas, Jaroslaw Z. Domagala, Rafal Jakiela +12
A range of high quality Ga1-xMnxN layers have been grown by molecular beam epitaxy with manganese concentration 0.2 < x < 10%, having the x value tuned by changing the growth tempe…
Fermi level and bands offsets determination in insulating (Ga,Mn)N/GaN structures
L. Janicki, G. Kunert, M. Sawicki +5
The Fermi level position in (Ga,Mn)N has been determined from the period-analysis of GaN-related Franz-Keldysh oscillation obtained by contactless electroreflectance in a series of…
Determination of the Fermi Level Position in Dilute Magnetic GaMnN Films
Stefan Barthel, Gerd Kunert, Mariuca Gartner +6
We report on a combined theoretical and experimental determination of the Fermi level position in wurtzite GaMnN films with and as grown by molecular…
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) ~…
GaMnN epitaxial films with high magnetization
Gerd Kunert, Sylwia Dobkowska, Tian Li +10
We report on the fabrication of pseudomorphic wurtzite GaMnN grown on GaN with Mn concentrations up to 10% using molecular beam epitaxy. According to Rutherford backscattering the…
