We have recently posted two new papers to the arXiv:
- “Raman Spectroscopy and Aging of the Low-Loss Ferrimagnet Vanadium Tetracyanoethylene” by H. F. H. Cheung, M. Chilcote, H. Yusuf, D. S. Cormode, Y. Shi, M. E. Flatté, E. Johnston-Halperin, and G. D. Fuchs. Here we use Raman spectrocopy correlated with ferromagnetic resonance and SQUID magnetometry to understand the processes that lead to chemical breakdown of the low-loss ferrimagnet V[TCNE]2. This material is exciting for coherent magnonics and quantum magnonics (see some ideas discussed here).
- “Nanoscale magnetization and current imaging using scanning-probe magneto-thermal microscopy” by Chi Zhang, Jason M. Bartell, Jonathan C. Karsch, Isaiah Gray, and Gregory D. Fuchs. Here we demonstrate a near-field scanning magneto-thermal microscope. This instrument can image both magnetization and current density with 100 nm scale spatial resolution and sub-100 ps scale temporal resolution. This is exciting because there is a dearth of magnetic microscopies that combine these two capabilities, and the ones that exist are mainly beamline techniques. Our approach is a table-top microscopy and comparably low cost.
Our paper, “Operando Control of Skyrmion Density in a Lorentz Transmission Electron Microscope with Current Pulses,” by A. M. Park, Z. Chen, X. S. Zhang, L. Zhu, D. A. Muller, and G. D. Fuchs has now been published in the Journal of Applied Physics. Congratulations Albert!
The Cornell Chronicle highlighted our paper demonstrating single quantum driving with acoustic waves: Acoustics put a fresh spin on electron transitions.
Our paper “Local Photothermal Control of Phase Transitions for On-Demand Room-Temperture Rewritable Magnetic Patterning” was featured on the inside cover of Advanced Materials and covered in the covered by the Cornell Chronicle.
Our paper, “Acoustically driving the single quantum spin transition of diamond nitrogen-vacancy centers” by H. Y. Chen, S. A. Bhave, and G. D. Fuchs is now out at Phys. Rev. Applied.
Congratulations to Dr. Huiyao Chen for successfully defending his thesis, “Quantum Acoustic Control of Diamond Nitrogen-Vacancy Centers.”
Our paper “Local photothermal control of phase transitions for on-demand room-temperature rewritable magnetic patterning,” by Antonio B. Mei*, Isaiah Gray*, Yongjian Tang, Jurgen Schubert, Don Werder, Jason Bartell, Daniel C. Ralph, Gregory D. Fuchs, and Darrell G. Schlom is now out at Advanced Materials.
Our paper, “Imaging uncompensated moments and exchange-biased emergent ferromagnetism in FeRh thin films,” by Isaiah Gray, Gregory M. Stiehl, John T. Heron, Antonio B. Mei, Darrell G. Schlom, Ramamoorthy Ramesh, Daniel C. Ralp and Gregory D. Fuchs is not out at Phyical Review Materials.
