Correlation between structure and electrical transport in ion-irradiated graphene grown on Cu foils
Grant Buchowicz, Peter R. Stone, Jeremy T. Robinson +3
Graphene grown by chemical vapor deposition and supported on SiO2 and sapphire substrates was studied following controlled introduction of defects induced by 35 keV carbon ion irra…
Compensation-dependent in-plane magnetization reversal processes in Ga1-xMnxP1-ySy
P. R. Stone, C. Bihler, M. Kraus +5
We report the effect of dilute alloying of the anion sublattice with S on the in-plane uniaxial magnetic anisotropy and magnetization reversal process in Ga1-xMnxP as measured by b…
Metal-insulator transition by isovalent anion substitution in Ga1-xMnxAs: Implications to ferromagnetism
P. R. Stone, K. Alberi, S. K. Z. Tardif +4
We have investigated the effect of partial isovalent anion substitution in Ga1-xMnxAs on electrical transport and ferromagnetism. Substitution of only 2.4% of As by P induces a met…
Tuning of ferromagnetism through anion substitution in Ga-Mn-pnictide ferromagnetic semiconductors
Peter R. Stone, Jeffrey W. Beeman, Kin M. Yu +1
We have synthesized Ga1-xMnxAs1-yPy and Ga1-xMnxP1-yNy by the combination of ion implantation and pulsed-laser melting. We find that the incorporation of isovalent impurities with…
Compositional tuning of ferromagnetism in Ga1-xMnxP
R. Farshchi, M. A. Scarpulla, P. R. Stone +7
We report the magnetic and transport properties of Ga1-xMnxP synthesized via ion implantation followed by pulsed laser melting over a range of x, namely 0.018 to 0.042. Like Ga1-xM…
Mn L3,2 X-ray Absorption Spectroscopy And Magnetic Circular Dichroism In Ferromagnetic (Ga,Mn)P
P. R. Stone, M. A. Scarpulla, R. Farshchi +7
We have measured the X-ray absorption (XAS) and X-ray magnetic circular dichroism (XMCD) at the Mn L3,2 edges in ferromagnetic Ga1-xMnxP films for 0.018<x<0.042. Large XMCD asymmet…
