Effects of tilted magnetocrystalline anisotropy on magnetic domains in Fe3Sn2 thin plates
Abstract
We studied effects of tilted magnetocrystalline anisotropy on the magnetic domains in a bubble-hosting magnet ${\mathrm{Fe}}_{3}{\mathrm{Sn}}_{2}$. With increasing the in-plane uniaxial magnetocrystalline anisotropy, the magnetic ground state in ${\mathrm{Fe}}_{3}{\mathrm{Sn}}_{2}$ thin plates changes from disordered stripe domains to stripe domains with preferred orientation. Through transport of intensity equation analysis, we further characterized the transition from skyrmion bubbles to biskyrmionlike configurations with increase in the tilted in-plane magnetocrystalline anisotropy when an out-of-plane magnetic field was applied. In addition, differential phase contrast scanning transmission electron microscopy (DPC-STEM) observations and micromagnetic simulations were carried out to confirm that the biskyrmionlike configurations were type-II bubbles. We show that, in addition tilting a magnetic field to induce misalignment between the magnetic field and the easy magnetization axis, tilting the uniaxial magnetic anisotropy can also be used to stabilize type-II bubbles. Our results also indicate DPC-STEM can help to distinguish between type-II bubbles and biskyrmions.

A previous study demonstrated the transformation of skyrmions to bubbles when the easy axis is tilted away from the out-of-plane direction.

Topologically trivial bubbles become the more stable phases because the magnetization along the easy uniaxial axis is favored by the domain wall magnetizations of the cylinder domains, minimizing the energy associated with the uniaxial magnetic anisotropy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
