Abstract

We present an investigation into the structural and magnetic properties of Zn-substituted Cu2OSeO3, a system
in which the skyrmion lattice (SkL) phase in the magnetic field–temperature phase diagram was previously
seen to split as a function of increasing Zn concentration. We find that splitting of the SkL is only observed in
polycrystalline samples and reflects the occurrence of several coexisting phases with different Zn content, each
distinguished by different magnetic behavior. No such multiphase behavior is observed in single-crystal samples.
