Analysis
This paper investigates the magnetocaloric effect (MCE) in a series of 6H-perovskite compounds, Ba3RRu2O9, where R represents different rare-earth elements (Ho, Gd, Tb, Nd). The study is significant because it explores the MCE in a 4d-4f correlated system, revealing intriguing behavior including switching between conventional and non-conventional MCE, and positive MCE in the Nd-containing compound. The findings contribute to understanding the interplay of magnetic ordering and MCE in these complex materials, potentially relevant for magnetic refrigeration applications.
Key Takeaways
- •The study focuses on the magnetocaloric effect (MCE) in Ba3RRu2O9 compounds.
- •Different rare-earth elements (Ho, Gd, Tb, Nd) are investigated.
- •The compounds exhibit interesting MCE behavior, including switching between conventional and non-conventional MCE.
- •Ba3NdRu2O9 shows positive MCE.
- •The findings are attributed to temperature-dependent spin reorientations and anisotropy.
