Compensation-dependence of magnetic and electrical properties in Ga1-xMnxP
T. E. Winkler, P. R. Stone, Tian Li +3
We demonstrate the control of the hole concentration in Ga1-xMnxP over a wide range by introducing compensating vacancies. The resulting evolution of the Curie temperature from 51…
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…
Electrical transport and ferromagnetism in Ga1-xMnxAs synthesized by ion implantation and pulsed-laser melting
M. A. Scarpulla, R. Farshchi, P. R. Stone +4
We present a detailed investigation of the magnetic and magnetotransport properties of thin films of ferromagnetic Ga1-xMnxAs synthesized using ion implantation and pulsed-laser me…
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…
Ferromagnetism in Ga1-xMnxP: evidence for inter-Mn exchange mediated by localized holes within a detached impurity band
M. A. Scarpulla, B. L. Cardozo, W. M. Hlaing Oo +2
We demonstrate that in ferromagnetic Ga1-xMnxP exchange is mediated by holes localized in a Mn-derived band. For x<0.06, infrared absorption and photoconductivity spectra indicate…
Fabrication of GaNxAs1-x Quantum Structures by Focused Ion Beam Patterning
K. Alberi, A. Minor, M. A. Scarpulla +5
A novel approach to the fabrication of GaNxAs1-x quantum dots and wires via ion beam patterning is presented. Photomodulated reflectance spectra confirm that N can be released from…
