“…INS experiments on a single-crystal sample of MnSc 2 S 4 grown with the chemical transport reaction technique 29 were performed on the cold-neutron three-axis spectrometer ThALES 49,50 at Institut Laue-Langevin (ILL) and the cold-neutron three-axis spectrometer PANDA 51,52 at Heinz Maier-Leibnitz Zentrum (MLZ). Five crystals with a total mass of ~100 mg were co-aligned with (hk0) as the horizontal scattering plane.…”

Magnetic skyrmions are topological solitons with a nanoscale winding spin texture that hold promise for spintronics applications [1][2][3][4] . Until now, skyrmions have been observed in a variety of magnets that exhibit nearly parallel alignment for the neighbouring spins, but theoretically, skyrmions with anti-parallel neighbouring spins are also possible. The latter, antiferromagnetic skyrmions, may allow more flexible control compared to the conventional ferromagnetic skyrmions 5-10 . Here, by combining neutron scattering and Monte Carlo simulations, we show that a fractional antiferromagnetic skyrmion lattice with an incipient meron character 11,12 is stabilized in MnSc2S4 through anisotropic couplings. Our work demonstrates that the theoretically proposed antiferromagnetic skyrmions can be stabilized in real materials and represents an important step towards implementing the antiferromagnetic-skyrmion based spintronic devices.
