Abstract
The search for room-temperature magnetocaloric materials for refrigeration has led to investigations of double perovskites. In particular, a puzzle has appeared in the La$_2$MnNiO$_6$, La$_2$MnCoO$_6$ and La$_2$MnFeO$_6$ family of compounds. They share the same crystal structure, but while La$_2$MnNiO$_6$ and La$_2$MnCoO$_6$ are ferromagnets below room temperature, La$_2$MnFeO$_6$, contrary to simple expectations, is a ferrimagnet. To solve this puzzle, we use density-functional theory calculations to investigate the electronic structure and magnetic exchange interactions of the ordered double perovskites. Our study reveals the critical role played by local electron-electron interaction in the Fe-$d$ orbital to promote the Fe$^{3+}$ valence state with half-filled $d$-shell over Fe$^{2+}$ and to establish a ferrimagnetic ground state for La$_2$MnFeO$_6$. The importance of Hund's coupling and Jahn-Teller distortion on the Mn$^{4+}$ ion is also pointed out. Exchange constants are extracted by comparing different magnetically ordered states. Mean-field and classical Monte-Carlo calculations on the resulting model give trends in $T_C$ that are in agreement with experiments on this family of materials.

###### Abstract
The search for room-temperature magnetocaloric materials for refrigeration has led to investigations of double perovskites. In particular, a puzzle has appeared in the La2MnNiO6, La2MnCoO6 and La2MnFeO6 family of compounds. They share the same crystal structure, but while La2MnNiO6 and La2MnCoO6 are ferromagnets below room temperature, La2MnFeO6, contrary to simple expectations, is a ferrimagnet. To solve this puzzle, we use density-functional theory calculations to investigate the electronic structure and magnetic exchange interactions of the ordered double perovskites. Our study reveals the critical role played by local electron-electron interaction in the Fe-d𝑑d orbital to promote the Fe3+ valence state with half-filled d𝑑d-shell over Fe2+ and to establish a ferrimagnetic ground state for La2MnFeO6. The importance of Hund’s coupling and Jahn-Teller distortion on the Mn4+ ion is also pointed out. Exchange constants are extracted by comparing different magnetically ordered states. Mean-field and classical Monte-Carlo calculations on the resulting model give trends in TCsubscript𝑇𝐶T\_{C} that are in agreement with experiments on this family of materials.
## I Introduction
The magnetocaloric effect leads to an increase of the temperature when certain materials are exposed to a magnetic field and decreases when they are removed from it. In order to be suitable for room temperature magnetic refrigeration, magnetocaloric materials need to exhibit a large change in magnetization around room temperature. The most interesting materials for this technology are hence ferromagnets with a high total moment per formula unit that undergo a magnetic phase transition to a paramagnetic state at room temperature.Gómez _et al._ ( [2013](https://ar5iv.labs.arxiv.org/html/1809.07812#bib.bib1 "")) Recently, double perovskite have been given considerable attention for this technology because of the low-production cost, stronger spin-phonon interactions, higher chemical stability, and better insulating properties.
