Tuning the Magnetic and Electronic Transport

Properties of Amorphous and Epitaxial FexSi1-x Thin Films for Spintronics

Spin-electronics or “spintronics” offers the potential to decrease power consumption relative to current CMOS technologies by utilizing the spin of an electron. A requisite for many spintronic devices is a material that can act as a spin-injector, and significant work has gone into identifying materials that can be utilized in this capacity. Stoichiometric Fe3Si has been touted as a potential option since it possesses a high Curie temperature and a theoretically predicted high spin polarization. The off-stoichiometry composition range, 0.45 < x < 0.75, in FexSi1-x is not well understood however, despite the fact this range offers the potential to use both chemical and structural order to significantly tune the properties, including possibly enhancing the spin-polarization. My work investigated amorphous and epitaxial FexSi1-x thin films in this composition range, and this talk with focus on the amorphous films, which exhibited numerous unexpected results. I will discuss film characterization including methods to determine the local atomic structure and chemical order. I will also show an unexpected enhancement in the magnetization of the amorphous films, both spin and orbital, with respect to crystalline films of the same composition. Finally, I will discuss electronic transport measurements and evidence of spin-polarized carriers from anomalous Hall effect measurements.

Hi All Physics Students,

If you want to be in the building after hours or weekends, the CSUEB police request that you have a building use permit. Nellie has these and I can sign them as Dept. Chair.

Dear Physics Majors graduating by June 2014,

Have you every wondered what it would be like to be a teacher? Do you have any idea what it would take to become a teacher or what teachers actually do?

If so, please join the Future Math and Science Teacher-Scholar Program.


The program offers $1000-$3000 scholarships for students to learn about K-12 teaching.

There are workshops and fun field trips!

Please go to the following link for more information:…/teacher-p…/support/fmstsp.html

Hope to see you at the first workshop in the Fall!
