Long Range and Short Range Magnetic Order in Orthorhombic LiMnO2

The magnetic properties of orthorhombic LiMnO2have been investigated in detail for the first time. The susceptibility data show several features including a Curie–Weiss regime from 600 to 800 K with θp=−1056(13) K and μeff=4.82 μB/Mn3+, a broad maximum at 360 K, and a field-cooled (FC), zero field cooled (ZFC) divergence below 100 K. The broad maximum indicates two-dimensional rather than one-dimensional short-range spin correlations. A Néel …
