RECENT NEWS AND RESEARCH HIGHLIGHTS
- Intrinsic anti-damping spin-orbit torque: in collaboration with Cambridge and Prague, we have predicted and observed a new type of spin-orbit coupling that shares its origin with the intrinsic spin-Hall effect and may have important consequences in future MRAM technology. arXiv:1306.1893 (2013), submitted to Nature Nanotechnology.
- Reading charge from spin-dynamics in topological insulators: exploiting the newly developed theory for spin-charge couple dynamics at the strong spin-orbit coupling limit, we predict a new type of phenomena that can shed light on the transport properties of the surface states of TIs. arXiv:1303.4478 (2013), accepted for publication in Phys. Rev. Lett.
- Theory of Spin Seebeck effect: in collaboration with Tinkonov and Finkelstein, we have developed the first quantitative theory of the non-local
behavior of spin Seebeck effect and proposed a novel contribution arising from its spectral non-uniform temperature distribution. Nature Communications 4, 1945 (2013).
- Scanned spin-precession microscopy: in collaboration with OSU, we demonstrate a new type of magnetic microscopy that connects state of the art imaging deconvolution techniques with nano-magnetic probe scanning imaging. This new technique complements optical techniques and is able to image buried interfaces. Phys. Rev. Lett. 111, 117201 (2013).
- Establishing micromagnetic parameters in GaMnAs: in a recent work lead experimentally in Prague, we determine the magnetic parameters consistently for the archetypical DMS, GaMnAs, Nature Communications 4, 1422 (2013) .
- New moves of the spintronics tango: our team has help in putting together a set of reviews of the hot emerging topics in spintronics and its close relationship to materials development and new phenomena. Nature Materials 11 368 (2012).
- Spin-Hall and non-local spin modulator: our team in collaboration with the Hitachi-Prague group, have implemented a device that performs spin-injection electrically and detects and manipulates the spin-Hall signal via a current.
Phys. Rev. Lett. 109 1076601 (2012).
- Spin Hall Transistor:
we have teamed with the Hitachi-Prague group to create the first Datta-Das spin FET AND-gate in the diffusive
regime (Science 330, 1801 (2010);College of Science press release).

Jairo Sinova's Curriculum Vitae
Welcome to the spintronics and nanoelectronics research group of Jairo
Sinova. As a condensed matter theory group we are interested on physical
phenomena of many body systems in which the behavior of the collective
system is quite different and unique from the behavior of its individual
components. Condensed matter physics is a vast field of physics which
provides endless opportunities. Our group has focused over the past few years on
the subfield of spintronics and mesoscopic electronic transport. These
fields study the effects coupling the spin and charge degrees of freedom
of the electron has on bulk properties of materials as well as transport and
optical phenomena. Some of our main contributions to this field are related
to spin Hall effects and diluted magnetic semiconductor physics. New avenues
are always opening ahead, with novel and unforeseen connections to other
points of views and topics.
TEACHING AND EDUCATION HIGHLIGHTS
Our group has developed the TAMU APPEAL program which
introduces a new methodology in teaching the sophemore level physics courses.
The goal is to reach a higher level of sophistication and a more physicist like approach to learning and
discovering physics which will help you build a smoother transition to the more advance courses.
All the material developed for the PHYS 221 course, including all the videos of the lectures, activities, and student interactions, together with descriptions of the implementation
and teaching techniques are available in the course website. This development was
primarely funded by NSF and the Research Corporation and done in collaboration with the developers of the
Paradigm Physics program.
GRADUATE MENTORING: PLANNING FOR SUCCESS
Success after PhD does not only entail great physics and science. Many things come into play and into the training that one needs to undertake. Planning for this sooner rather than later is important. I have given this talk to the incoming graduate students entitled "But nobody told me this", with the stream talk here. It contains the perfect recommendation which is up to the student to provide the ammunition to write; a strong motivator.
