Isaiah’s antiferromagnetic spin Seebeck imaging paper is now out at PRX
Isaiah’s paper, “Spin Seebeck Imaging of Spin-Torque Switching in Antiferromagnetic Pt/NiO Heterostructures” is now out at Phys. Rev. X. Congratulations Isaiah!
Huiyao’s diamond semiconfocal acoustic resonator paper is accepted at Nano Letters
Our paper “Engineering electron-phonon coupling of quantum defects to a semi-confocal acoustic resonator” by Huiyao Chen, Noah F. Opondo, Boyang Jiang, Evan R. MacQuarrie, Raphël S. Daveau, Sunil A. Bhave, and Gregory D. Fuchs has been accepted at Nano Letters.
DOE funds to help researchers reveal mysteries of magnetic materials
The Cornell Chronicle did a short piece on our recent DOE award for scanned-probe magneto-thermal microscopy of skyrmions: “DOE funds to help researchers reveal mysteries of magnetic materials.”
Several new papers are out
We have several new papers out for both diamond spins and magneto-thermal microscopy:
- “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. Ralph, and Gregory D. Fuchs is now posted on the arXiv. In this work we use magneto-thermal microscopy to study unusual exchange bias and ferromagnet-antiferromagnet coupling in FeRh.
- “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 was posted on the arXiv at the same time. In this we we demonstrate patterning ferromagnetism in FeRh at room temperature.
- “Engineering electron-phonon coupling of quantum defects to a semi-confocal acoustic resonator” by Huiyao Chen, Noah F. Opondo, Boyang Jiang, Evan R. MacQuarrie, Raphaël S. Daveau, Sunil A. Bhave, and Gregory D. Fuchs is on the arXiv. In this work we demonstrate a wavelength-scale bulk acoustic resonator in diamond that has enhanced spin-phonon coupling and optical collection.
- “Dual-frequency spin resonance spectroscopy of diamond nitrogen-vacancy centers in zero magnetic field” by A. K. Dmitriev†, H. Y. Chen†, G. D. Fuchs, A. K. Vershovskii is in press at Phys. Rev. A. In this work we model zero-field phenomena based on Landau-Zener-Stückelberg tunneling of diamond NV center ensembles.
