Jermain, Sriharsha V. Aradhya, Jack T. Brangham, Fengyuan Yang, Daniel C. Ralph, and Gregory D. Fuchs is now availible on the arXiv.

Our paper "Ferromagnetic resonance phase imaging in spin Hall multilayers," by Feng Guo, Jason M. Bartell, and Gregory D. Fuchs is now out at Phys. Rev. B.

Our recent paper "Continuous dynamical decoupling of a single diamond nitrogen-vacancy center spin with a mechanical resonator," by E. R. MacQuarrie, T. A. Gosavi, S. A. Bhave, and G. D. Fuchs was selected as an editor's suggestion at Phys. Rev. B.  Congratulations Evan!

Our paper "Polarization spectroscopy of defect-based single photon sources in ZnO" by N. R. Jungwirth, H. -S. Chang, M. Jiang, and G. D. Fuchs is out at ACS Nano.

Our paper "Polarization spectroscopy of defect-based single photon sources in ZnO" by N. R. Jungwirth, H. -S. Chang, M. Jiang, and G. D. Fuchs has been posted to the arXiv.  In this work we show that a yet unidentified single-defect based quantum emitter in ZnO has a Z-type optical dipole, which implies that it has orbital singlet states in both the ground and excited state.

Our paper "Phase-Sensitive Imaging of Ferromagnetic Resonance Using Ultrafast Heat Pulses" by Feng Guo, J. M. Bartell, D. H. Ngai, and G. D. Fuchs has now been published at Physical Review Applied, where it was selected as an editor's suggestion. 

Congratulations to Dr. Darryl Ngai, who successfully defended his thesis "Using Picosecond Heat Pulses to Measure Magnetization."

Congratulations to Isaiah Gray for being selected a graduate fellow of the Kavli Institute at Cornell for Nanoscale Science.  He will recieve the Watt W. Webb fellowship.

Our first paper in collaboration with Chris Ober's research group is now availible online at MRS communications.  In this work we use EPR spectroscopy to study the concentration of radical spins in block co-polymers with integrated TEMPO groups.

Our paper "Phase-sensitive imaging of ferromagnetic resonance using ultrafast heat pulses." by Feng Guo, J. M. Bartell, D. H. Ngai, and G. D. Fuchs is out at arXiv:1507.02303.

Two Fuchs group undergraduate researchers are graduating this week.  Hung-Shen Chang has earned a B.A. in Physics and Mingde (Jack) Jiang has earned a B.S.
