Quenched magnetic moment in Mn-doped amorphous Si (\textit{a}-MnSi) across the metal-insulator transition
Li Zeng, E. Helgren, R. Islam +4
The magnetic and electrical transport properties of Mn-doped amorphous silicon (\textit{a-}MnSi) thin films have been measured. The magnetic susceptibility obeys the…

The role of Cr substitution on the ferromagnetic properties of Ga1-xCrxN
R. K. Singh, Stephen Y. Wu, H. X. Liu +3
Angular-dependent channeling Rutherford Backscattering Spectroscopy (c-RBS) has been used to quantify the fraction of Cr atoms on substitutional, interstitial, and random sites in…

Observation of ferromagnetism above 900 K in Cr-GaN and Cr-AlN
H. X. Liu, Stephen Y. Wu, R. K. Singh +6
We report the observation of ferromagnetism at over 900K in Cr-GaN and Cr-AlN thin films. The saturation magnetization moments in our best films of Cr-GaN and Cr-AlN at low tempera…
