Abstract
Here, we report on imaging the spin texture of triple-Q magnetic order of Co1/3TaS2. The sample was measured with a low temperature STM (T=6K) under ultra-high vacuum with normal and spin-polarized tips. The STM images with the normal tip show the triangular lattice of the sample. The spin-polarized (SP) tip shows an additional symmetry related to the triple-Q ordering. In addition to that, the SP STM images revealed different spin textures with respect to the tip-spin orientation. The analysis suggests the presence of a phase difference between the tip and the triple-Q ordering of the sample.
This work gives a new insight into the exploration of chiral magnetic ordering with topological Hall effect using scanning probe microscopy.
