[en] Full text: Copper oxide materials generates huge interest ever since the discovery of superconductivity in YBCO. Recently it was discovered that Cu₂OSeO₃ is capable of hosting skyrmions, a rare skyrmion hosting system as most skyrmion system are metallic. A skyrmion is a topological stable particle-like object with the spin ordered in a vortex like fashion on the order of 50 nm. The skyrmion lattice forms in a narrow temperature and magnetic field range, forming a narrow pocket in the magnetic field-temperature phase diagram. Cu₂OSeO₃ is a multiferroic thus the individual skyrmions could be controlled through application of an external electric field. This offers the potential for a stable, more energy efficient, faster storage and retrieval of information in the application of data storage. Here we present the mapping of the skyrmion phase in bulk Cu₂OSeO₃ and Te-doped Cu₂OSeO₃ using SANS instrument QUOKKA at ANSTO. Mapping of the Te-doped showed that an enlarged stability range for the skyrmion phase. (author)
