Phonon-assisted formation of an itinerant electronic density wave
Jiaruo Li, Oleg Yu. Gorobtsov, Sheena K. K. Patel +13
Electronic instabilities drive ordering transitions in condensed matter. Despite many advances in the microscopic understanding of the ordered states, a more nuanced and profound q…
Quantum Sensing of Spin Transport Properties of an Antiferromagnetic Insulator
Hailong Wang, Shu Zhang, Nathan J. McLaughlin +6
Antiferromagnetic insulators (AFIs) are of significant interest due to their potential to develop next-generation spintronic devices. One major effort in this emerging field is to…
Energy-efficient generation of skyrmion phases in Co/Ni/Pt-based multilayers using Joule heating
Jeffrey A. Brock, Sergio A. Montoya, Mi-Young Im +1
We have studied the effects of electrical current pulses on skyrmion formation in a series of Co/Ni/Pt-based multilayers. Transmission X-ray microscopy reveals that by applying ele…
Anisotropic Ultrafast Spin Dynamics in Epitaxial Cobalt
Vivek Unikandanunni, Rajasekhar Medapalli, Eric E. Fullerton +3
We investigate the ultrafast spin dynamics in an epitaxial hcp(1100) cobalt thin film. By performing pump-probe magneto-optical measurements with the magnetization along either the…
Electrical Control of Coherent Spin Rotation of a Single-Spin Qubit
Xiaoche Wang, Yuxuan Xiao, Chuanpu Liu +7
Nitrogen vacancy (NV) centers, optically-active atomic defects in diamond, have attracted tremendous interest for quantum sensing, network, and computing applications due to their…
Shaping nanoscale magnetic domain memory in exchange-coupled ferromagnets by field cooling
Karine Chesnel, Alex Safsten, Matthew Rytting +1
The advance of magnetic nanotechnologies relies on detailed understanding of nanoscale magnetic mechanisms in materials. Magnetic domain memory (MDM), i.e., the tendency for magnet…
Femtosecond Photocurrents at the Pt/FeRh Interface
Rajasekhar Medapalli, Guanqiao Li, Sheena K. K. Patel +4
Femtosecond laser excitation of FeRh/Pt bilayers launches an ultrafast pulse of electric photocurrent in the Pt-layer and thus results in emission of electromagnetic radiation in t…
Direct measurement of temporal correlations above the spin-glass transition by coherent resonant magnetic x-ray spectroscopy
Jingjin Song, Sheena K. K. Patel, Rupak Bhattacharya +9
In the 1970s a new paradigm was introduced that interacting quenched systems, such as a spin-glass, have a phase transition in which long time memory of spatial patterns is realize…
Ultrafast perturbation of magnetic domains by optical pumping in a ferromagnetic multilayer
Dmitriy Zusin, Ezio Iacocca, Loïc Le Guyader +23
Ultrafast optical pumping of spatially nonuniform magnetic textures is known to induce far-from-equilibrium spin transport effects. Here, we use ultrafast x-ray diffraction with un…
Ultrafast kinetics of the antiferromagnetic-ferromagnetic phase transition in FeRh
G. Li, R. Medapalli, J. H. Mentink +7
Understanding how fast short-range interactions build up long-range order is one of the most intriguing topics in condensed matter physics. FeRh is a test specimen for studying thi…
