Periodicity staircase in a Fe/Gd magnetic thin film
Arnab Singh, Junli Li, Sergio A. Montoya +7
Presence of multiple competing periodicities may result in a system to go through states with modulated periodicities, an example of which is the self-similar staircase-like struct…
Room-temperature observation and current control of skyrmions in Pt/Co/Os/Pt thin films
R. Tolley, S. A. Montoya, E. E. Fullerton
We report the observation of room-temperature magnetic skyrmions in Pt/Co/Os/Pt thin-film heterostructures and their response to electric currents. The magnetic properties are extr…
Resonant properties of dipole skyrmions in amorphous Fe/Gd multilayers
S. A. Montoya, S. Couture, J. J. Chess +9
The dynamic response of dipole skyrmions in Fe/Gd multilayer films is investigated by ferromagnetic resonance measurements and compared to micromagnetic simulations. We detail thic…
Tailoring magnetic energies to form dipole skyrmions and skyrmion lattices
S. A. Montoya, S. Couture, J. J. Chess +11
The interesting physics and potential memory technologies resulting from topologically protected spin textures such as skyrmions, has prompted efforts to discover new material syst…
Colossal magnetic phase transition asymmetry in mesoscale FeRh stripes
Vojtech Uhlir, Jon Ander Arregi, Eric E. Fullerton
Coupled order parameters in phase-transition materials can be controlled using various driving forces such as temperature, magnetic and electric field, strain, spin-polarized curre…
Synthesizing Skyrmion Molecules in Fe-Gd Thin Films
J. C. T Lee, J. J. Chess, S. A. Montoya +9
We show that properly engineered amorphous Fe-Gd alloy thin films with perpendicular magnetic anisotropy exhibit room-temperature skyrmion molecules, or a pair of like-polarity, op…
Photoinduced Enhancement of the Charge Density Wave Amplitude
A. Singer, S. K. K. Patel, R. Kukreja +14
Symmetry breaking and the emergence of order is one of the most fascinating phenomena in condensed matter physics. It leads to a plethora of intriguing ground states found in antif…
Large exchange-dominated domain wall velocities in antiferromagnetically coupled nanowires
M. Kuteifan, M. V. Lubarda, S. Fu +5
Magnetic nanowires supporting field- and current-driven domain wall motion are envisioned for new methods of information storage and processing. A major obstacle for their practica…
All-optical control of ferromagnetic thin films and nanostructures
Charles-Henri Lambert, Stephane Mangin, B. S. D. Ch. S. Varaprasad +8
The interplay of light and magnetism has been a topic of interest since the original observations of Faraday and Kerr where magnetic materials affect the light polarization. While…
Ferromagnetic resonance linewidth in ultrathin films with perpendicular magnetic anisotropy
J-M. Beaujour, D. Ravelosona, I. Tudosa +2
Transition metal ferromagnetic films with perpendicular magnetic anisotropy (PMA) have ferromagnetic resonance (FMR) linewidths that are one order of magnitude larger than soft mag…
