2017 Workshop on Spins, Valleys, and Topological States in 2D and Layered Materials
Jun 4 – Jun 8 all-day
2017 Workshop on Spins, Valleys, and Topological States in 2D and Layered Materials @ Physics Research Building


The aim of the workshop is to bring together a leading group of researchers, in addition to students, postdocs and other participants, to discuss 2D platforms for spin, valley, and topological physics and their potential applications. With the continued evolution of graphene spintronics, combined with the recent advances in spin/valley-polarized excitations in transition metal dichalocogenides, and novel concepts related to the theory and synthesis of emerging new materials, there is a critical mass of researchers with complementary interests. In addition, monolayer magnetism and robust 2D topological states are important challenges moving forward.   At this workshop, participants will bring expertise from a variety of disciplines and discuss the latest advances in this growing field.

This workshop is supported by the Center for Emergent Materials (CEM) an NSF Materials Research Science and Engineering Center (MRSEC), the Institute of Complex and Adaptive Matter (ICAM), the Institute for Materials Research (IMR), and the Center for Exploration of Novel Complex Materials (ENCOMM).

Alumni Career Series: Morgan Welsh Bernier (JP Morgan Chase)
Sep 28 @ 11:30 am – 12:30 pm
Volunteer: Breakfast of Science Champions
Nov 11 @ 9:00 am – 12:00 pm

Volunteers Needed! Comets, craters and computer hard drives, oh my… The CEM and the CCAPP team up as students and teachers from local Columbus schools explore hands-on activities including a super conducting train exhibition, liquid nitrogen demonstrations, nanomagnetism and computer activities, snowballs and explosions in our solar system. Participants begin the morning by having breakfast with scientists and a visit to the planetarium; the rest of the morning is spent engaging in hands-on science activities. (Workshops last approximately 2.5 hours- including breakfast.) Prior to this event, volunteers visited the school to teach an astronomy lesson and following the event, the students returned to OSU for a planetarium visit and a career activity led by CCAPP volunteers.

Contact Michelle McCombs(.75) to volunteer.

“Vortices and skyrmions in nanopatterned magnetic structures”

In the first part of the talk our new results on magnetization dynamics of vortex-state circular nanodots with relatively large radius/thickness aspect ratio 0.25 – 0.7 will be presented. They can be summarized as:
1) A number of spin excitation modes were detected using broadband ferromagnetic resonance spectroscopy in the frequency range 0.5-6 GHz. The modes are found to be flexure oscillations of the vortex core string with n = 0,1,2… nodes along the dot thickness, i.e. higher-order gyrotropic modes.
2) It was established that above some thickness the intensity of more complicated n = 1 gyrotropic mode is unexpectedly higher than the one of n = 0 (uniform mode). The observed behavior is explained on the basis of the inhomogeneous vortex mode phase profiles.
3) With increase of dot thickness new azimuthal modes having curled structure at surfaces and radial nodes at dot central plane appear. Such complex structure of modes is a consequence of increasing thickness nonuniformity of effective field. These “curled” modes, in contrast with common uniform along dot thickness azimuthal modes, have a significant difference in the intensity between clockwise and counterclockwise modes of the same type.
In the second part a new route to obtain skyrmions and their arrays in relatively thick (up to 5 nm) continuous films of 3d magnetic metals at room temperature and in the absence of external magnetic fields will be discussed. It is based on the formation of strong vertical stray dipolar fields in the vicinity of film surface. Our micromagnetic simulations and analytical calculations demonstrate that this goal can be achieved by stacking two ferromagnetic subsystems – continuous film with in-plane anisotropy (where skyrmions will be formed) and antidot array with perpendicular anisotropy (stray fields will be created at the hole edges). By adjusting magnetizations and thicknesses of the layers, interlayer exchange coupling strength and hole diameters, different configurations for room temperature magnetic skyrmion arrays were obtained. Also, by introducing non-magnetic layer between two subsystems it is possible to create stable vortex-antivortex pairs with peculiar magnetic properties.
