Magnetic behavior in the series LaxY1−xTiO3

Single-phase products spanning the entire composition range LaTiO3YTiO3 were prepared. Magnetization-temperature data suggest a transition from negative Ti3+Ti3+ exchange interactions at the La-rich end to positive exchange interactions at the Y-rich end. The magnetic behavior of the intermediate compositions is complex and not well understood. Inverse susceptibility vs temperature data were fitted to a model including both a Curie-Weiss and …
