Topologically non trivial spin textures host great promise for futurespintronic applications. Skyrmions in particular are of burgeoning interestowing to their nanometric size, topological protection, and high mobility viaultra-low current densities. It has been previously reported through magneticsusceptibility, microscopy, and scattering techniques thatCo$_{8}$Zn$_{8}$Mn$_{4}$ forms an above room temperature triangular skyrmionlattice. Here we report the synthesis procedure and characterization of apolycrystalline Co$_{8}$Zn$_{8}$Mn$_{4}$ bulk sample. We employ powder x-raydiffraction, backscatter Laue diffraction, and neutron diffraction ascharacterization tools of the crystallinity of the samples, while magneticsusceptibility and Small Angle Neutron Scattering (SANS) measurements areperformed to study the skyrmion phase. Magnetic susceptibility measurementsshow a dip anomaly in the magnetization curves which persists over a range ofapproximately 305 K- 315 K. SANS measurements reveal a rotationally disorderedpolydomain skymrion lattice. Applying a recently developed symmetry-breakingmagnetic field sequence, we were able to orient and order the previously jammedstate to yield the prototypical hexagonal diffraction patterns, with secondarydiffraction rings.
