Origin of skyrmion lattice phase splitting in Zn-substituted Cu\(_{2}\)OSeO\(_{3}\)

We present an investigation into the structural and magnetic properties of Zn-substituted Cu\(_{2}\)OSeO\(_{3}\), 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...

Description
Summary:We present an investigation into the structural and magnetic properties of Zn-substituted Cu\(_{2}\)OSeO\(_{3}\), 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 behaviour. No such multiphase behaviour is observed in single crystal samples.
