Laser-Induced Skyrmion Writing and Erasing in an Ultrafast Cryo-Lorentz Transmission Electron Microscope

Henrik Moodysson Rønnow, Fabrizio Carbone, Ivan Madan, Giovanni Maria Vanacore, Enrico Pomarico, Gabriele Berruto, Ping Huang, Yoshie Murooka

We demonstrate that light-induced heat pulses of different duration and energy can write Skyrmions in a broad range of temperatures and magnetic field in FeGe. Using a combination of camera-rate and pump- probe cryo-Lorentz transmission electron microscopy ...

Magnetic Skyrmions and Skyrmion Clusters in the Helical Phase of Cu2OSeO3

Henrik Moodysson Rønnow, Fabrizio Carbone, Ping Huang, Yoshie Murooka

Skyrmions are nanometric spin whirls that can be stabilized in magnets lacking inversion symmetry. The properties of isolated Skyrmions embedded in a ferromagnetic background have been intensively studied. We show that single Skyrmions and clusters of Skyr ...

Simultaneous observation of the quantization and the interference pattern of a plasmonic near-field

Fabrizio Carbone, Brett Eugene Barwick, Yoshie Murooka, Luca Piazza, Tom Theodorus Antonius Lummen

Surface plasmon polaritons can confine electromagnetic fields in subwavelength spaces and are of interest for photonics, optical data storage devices and biosensing applications. In analogy to photons, they exhibit wave-particle duality, whose different as ...

Filming the formation and fluctuation of skyrmion domains by cryo-Lorentz transmission electron microscopy

Henrik Moodysson Rønnow, Marco Cantoni, Arnaud Magrez, Fabrizio Carbone, Edoardo Baldini, Jonathan White, Tatiana Latychevskaia, Ping Huang, Giulia Fulvia Mancini, Yoshie Murooka

Magnetic skyrmions are promising candidates as information carriers in logic or storage devices thanks to their robustness, guaranteed by the topological protection, and their nanometric size. Currently, little is known about the influence of parameters su ...
