Abnormal decrease in Curie temperature in pseudohalide rare-earth double perovskite ferroelastics driven by lanthanide contraction

Key Points

• Investigate how lanthanide contraction affects the properties of hybrid rare-earth double perovskites.
• Analyzed structural properties of hybrid rare-earth double perovskites (HREDPs).
• Examined the role of lanthanide contraction on the Curie temperature.
• Identified an abnormal decrease in Curie temperature related to lanthanide contraction.
• Proposed implications for the multifunctionality of HREDPs.
