Discovery of a large magnetic nonlinear Hall effect in an altermagnet
Lei Han, Xizhi Fu, Cheng Song +10
Since Edwin Halls groundbreaking discovery of the Hall effect in 1879, magnetism, spin, and quantization have been expanding the scope of Hall effects, continuously driving transfo…
Unravelling the Local Crystallographic Structure of Ferromagnetic GaFeN Nanocrystals Embedded in GaN
A. Navarro-Quezada, K. Gas, A. Spindlberger +4
In the Fe-doped GaN phase-separated magnetic semiconductor GaFeN, the presence of embedded GaFeN nanocrystals determines the magnetic properties of the system. Here, th…
Magnetotransport in phase-separated (Ga,Fe)N with '-GaFeN nanocrystals
A. Navarro-Quezada, M. Aiglinger, B. Faina +6
The magnetotransport in phase-separated (Ga,Fe)N containing '-GaFeN (0\,\,y\,1) nanocrystals (NCs) is studied in the temperature range between 2\,K and 300\,K.…
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…
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…
