Critical slowing of the spin and charge density wave order in thin film Cr following photoexcitation
Sheena K. K. Patel, Oleg Yu. Gorobtsov, Devin Cela +11
We report on the evolution of the charge density wave (CDW) and spin density wave (SDW) order of a chromium film following photoexcitation with an ultrafast optical laser pulse. Th…
Ultrafast Emergence of Ferromagnetism in Antiferromagnetic FeRh in High Magnetic Fields
I. A. Dolgikh, T. G. H. Blank, A. G. Buzdakov +11
Ultrafast heating of FeRh by a femtosecond laser pulse launches a magneto-structural phase transition from an antiferromagnetic to a ferromagnetic state. Aiming to reveal the ultra…
Dynamic symmetry breaking in chiral magnetic systems
Jeffrey A. Brock, Michael D. Kitcher, Pierre Vallobra +6
The Dzyaloshinskii-Moriya interaction (DMI) in magnetic systems stabilizes spin textures with preferred chirality, applicable to next-generation memory and computing architectures.…
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…
THz emission from Co/Pt bilayers with varied roughness, crystal structure, and interface intermixing
G. Li, R. Medapalli, R. V. Mikhaylovskiy +4
Femtosecond laser excitation of a Co/Pt bilayer results in the efficient emission of picosecond THz pulses. Two known mechanisms for generating THz emission are spin-polarized curr…
Helicity-dependent all-optical domain wall motion in ferromagnetic thin films
Y. Quessab, R. Medapalli, M. S. El Hadri +4
Domain wall displacement in Co/Pt thin films induced by not only fs- but also ps-laser pulses is demonstrated using time-resolved magneto-optical Faraday imaging. We evidence multi…
Mechanism of all-optical control of ferromagnetic multilayers with circularly polarized light
Rajasekhar Medapalli, Dymtro Afanasiev, Dokyun Kim +6
Time-resolved imaging reveals that the helicity dependent all-optical switching (HD-AOS) of Co/Pt ferromagnetic multilayers proceeds by two stages. First one involves the helicity…
