Cu${}_{2}$OSeO${}_{3}$ is an insulating skyrmion host material with a magnetoelectric coupling giving rise to electric polarization. Using magnetic force microscopy on the surface of a bulk single crystal, the authors study here the helical real-space spin structure and its reorientation under applied magnetic field. Using Kelvin probe force microscopy, they also measure the field dependency of the electric polarization originating in this reorientation process. An effective Landau theory…

Tunable cooperativity in coupled spin-cavity systems

We experimentally study the tunability of the cooperativity in coupled spin--cavity systems by changing the magnetic state of the spin system via an external control parameter. As model system, we

The magnetic phases of cubic chiral ferromagnets with the Dzyaloshinskii–Moriya interaction (MnSi, Cu2OSeO3) are studied in terms of microscopic and phenomenological approaches. The interaction of

Chiral surface spin textures in Cu2OSeO3 unveiled by soft X-ray scattering in specular reflection geometry

ABSTRACT Resonant elastic soft X-ray magnetic scattering (XRMS) is a powerful tool to explore long-periodic spin textures in single crystals. However, due to the limited momentum transfer range



Heuristic Description of Magnetoelectricity of Cu2OSeO3.

A heuristic description of the magnetoelectric properties in CuO2SeO3 is developed and the model successfully describes the dependency of the electric polarization on the magnetization in all magnetically modulated phases.

Multidomain Skyrmion Lattice State in Cu2OSeO3.

A controlled way is reported of creating a multidomain skyrmion state near the surface of a Cu2OSeO3 single crystal, observed by soft resonant elastic X-ray scattering, which is an ideal tool to probe the magnetic order at the L3 edge of 3d metal compounds giving an average depth sensitivity of ∼50 nm.

Long-wavelength helimagnetic order and skyrmion lattice phase in Cu2OSeO3.

A long-wavelength helimagnetic superstructure in bulk samples of the ferrimagnetic insulator Cu2OSeO3 is reported, providing putative evidence for effective spin currents as the origin of enhancements of the magnetodielectric response instead of atomic displacements considered so far.

Magnetoelectric coupling in the cubic ferrimagnet Cu(2)OSeO(3)

We have investigated the magnetoelectric coupling in the lone pair containing piezoelectric ferrimagnet Cu(2)OSeO(3). Significant magnetocapacitance develops in the magnetically ordered state (T(c) =

Magnetoelectric nature of skyrmions in a chiral magnetic insulator Cu2OSeO3

Dielectric properties were investigated under various magnitudes and directions of magnetic field (H) for a chiral magnetic insulator Cu2OSeO3. We found that the skyrmion crystal induces electric

New magnetic phase of the chiral skyrmion material Cu2OSeO3

A new magnetic phase is reported in the chiral magnet, Cu2OSeO3, which is predicted to affect its physical properties and its multiferroic properties, and a remarkable deviation from this universal behavior is reported.

A mean-field theory of spin-density-wave wavevector and polarisation vector rotation induced by the application of a magnetic field to MnSi in its spin-density-wave phase, and a prediction of the

Local dynamics of topological magnetic defects in the itinerant helimagnet FeGe

The observation of stochastic instabilities in the micromagnetic structure provides insight to the spatio-temporal dynamics of itinerant helimagnets and topological defects, and discloses open challenges regarding their technological usage.

Symmetry breaking, slow relaxation dynamics, and topological defects at the field-induced helix reorientation in MnSi

The Dzyaloshinskii-Moriya interaction in the cubic chiral magnet MnSi stabilizes a magnetic helix - a periodic one-dimensional modulation of the magnetization. The orientation of this helix is

How to measure the local Dzyaloshinskii-Moriya Interaction in Skyrmion Thin-Film Multilayers

This work’s magnetic force microscopy studies of magnetron-sputtered Ir/Co/Pt-multilayers show skyrmions that are smaller than previously observed, are not circularly symmetric, and are pinned to 50-nm wide areas where the DM interaction is higher than average.
