Research Abstract

Lanthanide complexes have attracted attention as designable magnetic, luminescent materials, and catalysts. However, the applications as magnetic materials are limited because almost all of lanthanide complexes are paramagnets. In this study, we succeeded in the synthesis of three dimensional network lanthanide complex showing ferromagnetism. To our knowledge, this is the first example that a monometallic lanthanide complex shows a ferromagnetic phase transition.
