Studies of single doping of Mn and Fe in Si to deduce simple guidelines in selecting transition metal elements for growing Si-based spintronic materials (2009)

Shaughnessy, Michael, Fong, C. Y., Snow, Ryan, Yang, L. H., Chen, X. S., Zhiang, Z. M.

Single dopings of Mn and Fe in Si are investigated using 8-, 64-, and 216-atom supercells and a first-principles method based on density functional theory. Atomic sizes play an essential role in...

Origin of large moments in MnxSi1−x at small x (2009)

Shaughnessy, M., Fong, C. Y., Snow, Ryan, Liu, Kai, Pask, J. E., Yang, L. H.

Recently, the magnetic moment/Mn, M, in MnxSi1−x was measured to be 5.0 Bohr magneton/Mn, at x=0.1%. To understand this observed M, we investigate several MnxSi1−x models of alloys using...

Origin of large moments in Mn$_x$Si$_{1-x}$ at small x (2009)

Shaughnessy, Michael, Fong, C. Y., Snow, Ryan, Liu, Kai, Pask, John, Yang, Lin H.

Recently, the magnetic moment/Mn, $M$, in Mn$_x$Si$_{1-x}$ was measured to be 5.0 $\mu_B$/Mn, at $x$ =0.1%. To understand this observed $M$, we investigate several Mn$_x$Si$_{1-x}$ models of alloys...
