In addition to complex spin-ice and spin-liquid states of rare-earth pyrochlore oxides, AIrO iridates have been recently proposed to host a cooling-field-controllable antiferromagnetic domain structure of iridium moments. Reliable and profound studies of the magnetic domain structure, including domains' interfaces, have been frequently limited by insufficient sample quality or lack of single crystals. We report the magnetic properties of the for-the-first-time synthesised LuIrO and ErIrO single crystals; focussing on the robust ferromagnetic component of magnetisation present in the material with the antiferromagnetically ordered state of the all-in-all-out (AIAO) type.

- The study investigates how pressure affects the magnetic properties of stoichiometric Ni2MnSn structures, highlighting discrepancies between theoretical calculations and experimental results in magnetic moments.
- The research particularly examines the impact of point defects, such as swapping of Mn and Ni atoms, on these magnetic properties and how they alter the overall magnetic moments compared to the defect-free structures.
- Significant variations in pressure-induced changes in magnetic moments are observed, revealing complex behaviors in both ferromagnetic and anti-ferromagnetic states, despite their similar energy formation levels.
