Magnetic and structural properties of Ni-substituted magnetoelectric Co4Nb2O9

Henrik Moodysson Rønnow, Ivica Zivkovic, Virgile Yves Favre, Hadi Papi, Hossein Ahmadvand

The magnetic and structural properties of polycrystalline Co4-xNixNb2O9 (x = 1, 2) have been investigated by neutron powder diffraction, magnetization and heat capacity measurements, and density functional theory (DFT) calculations. For x = 1, the compound ...

Correlation between site occupancies and spin-glass transition in skyrmion host Co10-x/2Zn10-x/2Mnx

Henrik Moodysson Rønnow, Jonathan White

Ternary alloys Co-Zn-Mn with beta-Mn-type structure exhibit helimagnetic order and skyrmion lattice states in a low-Mn-concentration region. Recent studies on Co10-x/2Zn10-x/2Mnx (CZM) revealed that the magnetic modulation period and the paramagnetic-to-he ...

Strain-engineering Mott-insulating La2CuO4

Henrik Moodysson Rønnow, Johan Juul Chang, Yu-Pei Tseng, Noore Elahi Shaik, Yi Tseng, Thorsten Schmitt

The transition temperature T-c of unconventional superconductivity is often tunable. For a monolayer of FeSe, for example, the sweet spot is uniquely bound to titanium-oxide substrates. By contrast for La2-xSrxCuO4 thin films, such substrates are sub-optim ...

Deformation of the moving magnetic skyrmion lattice in MnSi under electric current flow

Henrik Moodysson Rønnow, Ivica Zivkovic, Jonathan White, Zhuo Quan Im

Topological defects are found ubiquitously in various kinds of matter, such as vortices in type-II superconductors, and magnetic skyrmions in chiral ferromagnets. While knowledge on the static behavior of magnetic skyrmions is accumulating steadily, their ...

Direct electric field control of the skyrmion phase in a magnetoelectric insulator

Henrik Moodysson Rønnow, Ivica Zivkovic, Jonathan White

Magnetic skyrmions are topologically protected spin-whirls currently considered as promising for use in ultra-dense memory devices. Towards achieving this goal, exploration of the skyrmion phase response and under external stimuli is urgently required. Her ...

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

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

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 ...

Probing multi-spinon excitations outside of the two-spinon continuum in the antiferromagnetic spin chain cuprate Sr2CuO3

Martin Mourigal, Henrik Moodysson Rønnow, Thorsten Schmitt

One-dimensional (1D) magnetic insulators have attracted significant interest as a platform for studying quasiparticle fractionalization, quantum criticality, and emergent phenomena. The spin-1/2 Heisenberg chain with antiferromagnetic nearest neighbour int ...

Disordered skyrmion phase stabilized by magnetic frustration in a chiral magnet

Henrik Moodysson Rønnow, Jonathan White

Magnetic skyrmions are vortex-like topological spin textures often observed to form a triangular-lattice skyrmion crystal in structurally chiral magnets with the Dzyaloshinskii-Moriya interaction. Recently, beta-Mn structure-type Co-Zn-Mn alloys were ident ...

Negative-pressure-induced helimagnetism in ferromagnetic cubic perovskites Sr1-xBaxCoO3

Henrik Moodysson Rønnow, Jonathan White

Helimagnetic materials are identified as promising for novel spintronic applications. Since helical spin order is manifested as a compromise of competing magnetic exchange interactions, its emergence is limited by unique constraints imposed by the crystall ...
