On Curie temperature of B20-MnSi films
Zichao Li, Ye Yuan, Viktor Begeza +5
B20-type MnSi is the prototype magnetic skyrmion material. Thin films of MnSi show a higher Curie temperature than their bulk counterpart. However, it is not yet clear what mechani…
B20-MnSi films grown on Si(100) substrates with magnetic skyrmion signature
Zichao Li, Ye Yuan, René Hübner +8
Magnetic skyrmions have been suggested as information carriers for future spintronic devices. As the first material with experimentally confirmed skyrmions, B20-type MnSi was the r…
p-type codoping effect in (Ga,Mn)As: Mn lattice location versus magnetic properties
Chi Xu, Chenhui Zhang, Mao Wang +7
In the present work, we perform a systematic investigation on p-type codoping in (Ga,Mn)As. Through gradually increasing Zn doping concentration, the hole concentration increases,…
Hole compensation effect in III-Mn-V dilute ferromagnetic semiconductors
Chi Xu, Mao Wang, Ye Yuan +3
A systematic study of hole compensation effect on magnetic properties, which is controlled by defect compensation through ion irradiation, in (Ga,Mn)As, (In,Mn)As and (Ga,Mn)P is p…
Superconductivity in single-crystalline, aluminum- and gallium-hyperdoped germanium
Slawomir Prucnal, Viton Heera, René Hübner +11
Superconductivity in group IV semiconductors is desired for hybrid devices combining both semiconducting and superconducting properties. Following boron doped diamond and Si, super…

Yufang Xie, Ye Yuan, Mao Wang +7
Mn5Ge3 thin films have been demonstrated as a promising spin-injector material for germanium-based spintronic devices. So far, Mn5Ge3 has been grown epitaxially only on Ge (111) su…
Magnetocrystalline anisotropy and exchange probed by high-field anomalous Hall effect in fully-compensated half-metallic Mn2RuxGa thin films
Ciarán Fowley, Karsten Rode, Yong-Chang Lau +12
Magnetotransport is investigated in thin films of the half-metallic ferrimagnet MnRuGa in pulsed magnetic fields of up to 58 T. A non-vanishing Hall signal is observed over…
CMOS-compatible controlled hyperdoping of silicon nanowires
Yonder Berencén, Slawomir Prucnal, Wolfhard Möller +13
Hyperdoping consists of the intentional introduction of deep-level dopants into a semiconductor in excess of equilibrium concentrations. This causes a broadening of dopant energy l…
Electronic phase separation in insulating (Ga,Mn)As with low compensation: Super-paramagnetism and hopping conduction
Ye Yuan, Mao Wang, Chi Xu +6
In the present work, low compensated insulating (Ga,Mn)As with 0.7% Mn is obtained by ion implantation combined with pulsed laser melting. The sample shows variable-range hopping t…
Towards diluted magnetism in TaAs
Yu Liu, Zhilin Li, Liwei Guo +10
Magnetism in Weyl semimetals is desired to investigate the interaction between the magnetic moments and Weyl fermions, e.g. to explore anomalous quantum Hall phenomena. Here we dem…
Interplay between localization and magnetism in (Ga,Mn)As and (In,Mn)As
Ye Yuan, Chi Xu, René Hübner +6
Ion implantation of Mn combined with pulsed laser melting is employed to obtain two representative compounds of dilute ferromagnetic semiconductors (DFSs): Ga1-xMnxAs and In1-xMnxA…

Hyper doping Si with up to 6 at.% Ti in solid solution was performed by ion implantation followed by pulsed laser annealing and flash lamp annealing. In both cases, the implanted S…
Precise tuning of the Curie temperature of (Ga,Mn)As-based magnetic semiconductors by hole compensation: Support for valence-band ferromagnetism
Shengqiang Zhou, Lin Li, Ye Yuan +11
For the prototype diluted ferromagnetic semiconductor (Ga,Mn)As, there is a fundamental concern about the electronic states near the Fermi level, i.e., whether the Fermi level resi…
