In Situ Electric Field Skyrmion Creation in Magnetoelectric Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Fabrizio Carbone, Marco Cantoni, Ping Huang, Oleksandr Kriuchkov, Rajeswari Jayaraman

Exploiting additional degrees of freedom in solid-state materials may be the most-promising solution when approaching the quantum limit of Moore's law for the conventional electronic industry. Recently discovered topologically nontrivial spin textures, sky ...

Single crystals of superconducting SmFeAsOHx: Structure and properties

László Forró, Alla Arakcheeva, Richard Gaal, Sergiy Katrych, Andrea Pisoni, Ping Huang, Péter Krisztián Matus

We report the synthesis, structure, and superconducting properties of single crystals of SmFeAsOHx. The crystals were grown at high pressure and high temperature using a cubic anvil technique. H-1-NMR studies confirm the presence of H atoms in the samples. ...

MnO nanoparticles as the cause of ferromagnetism in bulk dilute Mn-doped ZnO

Henrik Moodysson Rønnow, Arnaud Magrez, Diane Virginie Marie Lançon, Ping Huang

We show that the observed ferromagnetic behavior of ZnO lightly doped with Mn coincides with the presence of MnO nanoparticles, whereas cluster-free Mn doped ZnO behaves paramagnetically. This conclusion is reached by a study of the structural and magnetic ...

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

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

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 ...

Melting of a skyrmion lattice to a skyrmion liquid via a hexatic phase

Henrik Moodysson Rønnow, Arnaud Magrez, Fabrizio Carbone, Marco Cantoni, Ping Huang, Thomas Schönenberger

While in 3D materials melting is a single, first-order phase transition, in 2D systems, it can also proceed via an intermediate phase. For a skyrmion lattice in Cu2OSeO3, magnetic field variations can tune this quasiparticle 2D solid into a skyrmion liquid ...

Control of Topological Magnetic Textures by Magnetic and Electric Fields in Magnetoelectric Helimagnet Cu₂OSeO₃

Ping Huang

Magnetic skyrmions, topologically non-trivial chiral whirl-like spin configurations, have been under massive investigations in both fundamental and application aspects. In some special compounds, these quasi-particles can formtriangular skrymion lattice (S ...

Electric-Field-Induced Skyrmion Distortion and Giant Lattice Rotation in the Magnetoelectric Insulator Cu2OSeO3

Helmuth Berger, Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Jonathan White, Krunoslav Prsa, Ping Huang, Arash Alahgholipour Omrani

Uniquely in Cu2OSeO3, the Skyrmions, which are topologically protected magnetic spin vortexlike objects, display a magnetoelectric coupling and can be manipulated by externally applied electric (E) fields. Here, we explore the E-field coupling to the magne ...

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 ...

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 ...

Spin excitations in the skyrmion host Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Jonathan White, Peter Babkevich, Felix Groitl, Gregory Scott Tucker, Ping Huang

We have used inelastic neutron scattering to measure the magnetic excitation spectrum along the high-symmetry directions of the first Brillouin zone of the magnetic skyrmion hosting compound Cu2OSeO3. The majority of our scattering data are consistent with ...

Superparamagnetic Nanoparticles as High Efficiency Magnetic Resonance Imaging T-2 Contrast Agent

Francesco Stellacci, Henrik Moodysson Rønnow, Kurt Schenk, Paulo Henrique Jacob Silva, Randy Patrick Carney, Lin Yang, Ping Huang, Arash Alahgholipour Omrani

Nanoparticle-based magnetic resonance imaging T-2 negative agents are of great interest, and much effort is devoted to increasing cell loading capability while maintaining low cytotoxicity. Herein, two classes of mixed-ligand protected magnetic-responsive, ...
