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:
Hope to see you at the first workshop in the Fall!
Spread the word, get CSUEB physics more likes from other colleagues and other students in your major. This way we can start posting upcoming seminars and events.
