Ilmenite-type Ca IrO3 via topochemical ion exchange: Stacking faults and low-temperature magnetic anomaly

Key Points

• Low-temperature magnetic anomalies occur in Ca IrO3, indicating significant magnetic behavior changes.
• Magnetization measurements reveal a pivotal shift around 10 K, reflecting stacking faults' impact.
• Topochemical ion exchange was used to synthesize ilmenite-type Ca IrO3 from precursor materials.
• Findings highlight unique stacking faults in Ca IrO3, which may influence its magnetic properties.
