Mn 1.4 PtSn is the first material in which antiskyrmions have been observed in ultra-thin single crystalline specimens. While bulk crystals exhibit fractal patterns of purely ferromagnetic domain ordering at room temperature, ultra-thin Mn 1.4 PtSn lamellae clearly show antiskyrmion lattices with lattice spacings up to several µ m. In the work presented here, we systematically investigate the thickness region from 400 nm to 10 µ m using 100 × 100 µ m 2 -wide Mn 1.4 PtSn plates, and identify the…

Anisotropic fractal magnetic domain pattern in bulk Mn1.4PtSn

The tetragonal compound Mn$_{1.4}$PtSn with the $D_{2d}$ symmetry recently attracted attention as the first known material that hosts magnetic antiskyrmions, which differ from the so far known

Tunable Magnetic Antiskyrmion Size and Helical Period from Nanometers to Micrometers in a D2d Heusler Compound

It is shown by real-space magnetic imaging that the helix period λ and the size of the antiskyrmion daSk in the D2d compound Mn1.4 PtSn can be systematically tuned by more than an order of magnitude from ≈100 nm to more than 1.1 µm  by varying the thickness of the lamella in which they are observed.

Elliptical Bloch skyrmion chiral twins in an antiskyrmion system

It is shown, using Lorentz transmission electron microscopy, that arrays of skyrmion can be stabilized in a tetragonal inverse Heusler with D 2d symmetry whose Dzyaloshinskii-Moriya interaction (DMI) otherwise supports antiskyrmions.

Controlled transformation of skyrmions and antiskyrmions in a non-centrosymmetric magnet

Modulations of the orientation and strength of an in-plane magnetic field induces the transformation from antiskyrmions to non-topological bubbles and skyrmion and their lattices in a non-centrosymmetric Heusler magnet, with D 2d symmetry.

Observation of Magnetic Antiskyrmions in the Low Magnetization Ferrimagnet Mn2Rh0.95Ir0.05Sn

This work reports the observation of antiskyrmions in a second inverse tetragonal Heusler compound, Mn2Rh0.95Ir0.05Sn, which can be formed stoichiometrically without any Mn vacancies and which thus exhibits a much smaller magnetization.

Intrinsic stability of magnetic anti-skyrmions in the tetragonal inverse Heusler compound Mn1.4Pt0.9Pd0.1Sn

It is shown, using Lorentz transmission electron microscopy, that anti-skyrmions are found over a wide range of temperature and magnetic fields in wedged lamellae formed from single crystals of Mn1.4Pt0.9Pd0.1Sn for thicknesses ranging up to ~250 nm.
