Search for new Skyrmion states in Co6.75Zn6.75Mn6.5

DOI

Magnetic Skyrmions are topological magnetic spin-vortex-like objects that form in chiral magnets. In the recently discovered Skyrmion hosts CoxZnyMnz alloys, the randomness of site occupancies provides a potential landscape with a disorder strength that can be tuned according to the composition. This makes certain CoxZnyMnz alloys as candidates for hosting new Skyrmion states that are only realisable in the presence of certain levels of disorder, such as Skyrmion glass-like states. Here we propose a D33 SANS study of the microscopic magnetic correlations in the alloy Co6.75Zn6.75Mn6.5. Our preliminary zero field SANS data on this compound show the formation of both helical and helical glass-like states, and unusual T-dependent behaviour on cooling. With this proposal our goals are i) to characterise the microscopic magnetic phase diagram of this material under finite magnetic field, and ii) to search for evidence of a Skyrmion glass state. Proving the latter would be important due to the ongoing debate as to whether crystallographic concepts can strictly be explored in Skyrmion states.
