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…
Crystal field model simulations of magnetic response of pairs, triplets and quartets of Mn ions in GaN
D. Sztenkiel, K. Gas, J. Z. Domagala +2
A ferromagnetic coupling between localized Mn spins was predicted in a series of \textit{ab initio} and tight binding calculations and experimentally verified for the dilute magnet…
Raman scattering studies of the lateral Mn distribution in MBE-grown Ga1-xMnxN epilayers
Katarzyna Gas, Detlef Hommel, Maciej Sawicki
Recent interest in very thin single phase Ga1-xMnxN dilute magnetic layers increased needs for precise, non-destructive, and relatively fast characterization methods with key issue…
Electrical characteristics of vertical-geometry Schottky junction to magnetic insulator (Ga,Mn)N heteroepitaxially grown on sapphire
Karolina Kalbarczyk, Krzysztof Dybko, Katarzyna Gas +7
Schottky barrier height and the ideality factor are established for the first time in the single phase (Ga,Mn)N using a vertical geometry device. The material has been heteroep…
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…
