Abstract
In this work, it is shown that when replacing Ge by Fe in Tb5Si2Ge2 the structural transition still
occurs and enhances the Magnetocaloric effect (up to 66%) with maximum of MCE at a critical Fe
amount where the magnetic and structural transitions become fully coupled. It is observed that Fe
concentration is able to mimic the e?ect of external pressure as it induces a complex microstructure,
that tunes long range strain ?elds. This knowledge is crucial for the development of strategies
towards materials with improved performance for e?cient magnetic refrigeration applications.
