“…See figure S2 to see the M(T) curves for the different samples. The MnB sample (represented by black and square symbols) yields a maximum isothermal magnetic entropy change ( ∆S max isothermal ) of 3.36 J kg −1 K −1 at 572 K (1 T), which amounts to 6.0 J kg −1 K −1 when extrapolated to 2 T using power law fits to the magnetic field dependence of |∆Sisothermal| (which was reported and verified in [45][46][47]). These values are similar to those reported in [8].…”

In most cases, substitution studies that aim to optimize magnetic properties are performed at the magnetic atomic site. However, in the case of MnB, magnetic substitutions at the Mn site significantly decrease the once promising magnetocaloric and magnetic properties. This study employs computationally directed search to optimize the magnetocaloric properties of MnB where partial substitutions of boron atoms (MnB1-xSix and MnB1-xGex where x = 0.3125, 0.625, and 0.125) reveal new compounds with a greater magnetocaloric effect than pure MnB at the same Curie temperature. These new compounds were obtained by arc melting the pure elements and further characterized. The computationally driven screening process is based on density functional theory calculations that do not require large databases of known compounds. This work demonstrates that using simple computational screening procedures to search for new magnetocaloric materials with improved properties can be done quickly, cost-effectively, and while maintaining reliability.

“…Similarly, the coefficient of performance (COP) offers a more precise tool than RC and RCP for evaluating the energy conversion of the materials as it also accounts for magnetization hysteresis during working conditions and allows comparison among different cooling technologies. 46 However, this magnitude is also scarcely reported in publications. A recent overview of magnetocaloric measurement techniques, together with their application to the study of phase transitions, is presented in ref.…”

<p>The expected energy transition to hydrogen gas as a greener energy vector has revived the interest in magnetic refrigeration at the cryogenic range, specifically between 20 and 80 K, with the vision to develop a new generation of hydrogen gas liquefiers. From the materials science point of view, the search for magnetocaloric materials containing mainly non-critical elements with a significant response in that temperature range, together with good cyclability and stability, is a challenging task. Given the increasing interest of the research community on this topic, we aim to establish a comprehensive catalog of the magnetocaloric compounds characterized so far, to be used as a starting point for further research. For this purpose, a systematic outlook of the state of the art is presented here, with the analysis and classification of more than 400 cryogenic magnetocaloric materials, divided into five large families according to their physicochemical properties. Moreover, we provide detailed information about their magnetocaloric properties, magnetic behavior, and transition characteristics together with criticality, which will facilitate the future search for optimal compounds.</p>

“…Accordingly in 2016, [150] S. Tumanski wrote a very complete book about magnetic measurements which can be completed by a book chapter by J. M. Rawson et al (2017) [151] and the comprehensive collective book edited by B. Dodrill et al in 2021. [152] Parts dedicated to molecular materials can be considered as updates from C. J. O'Connor book chapter about measurements in magnetochemistry in 1982; [153] techniques evolved but main concepts remain unchanged. These references are not specific to SMM but will allow the reader to understand the main measurement principles and avoid common pitfalls such as the units used in molecule magnetism, etc.… As far as magnetic characterization of 4 f-SMM is concerned specific techniques emerged and one may focus on the very complete book chapter written in 2015, [154] by R. Clérac et al…”

The number of scientific articles that need to be considered to cover a research topic is ever‐increasing and quite difficult for a newcomer to assimilate. This is particularly true in dynamic discipline like Molecular Magnetism. In order to help young researchers in this field, this article proposes a "review of reviews" also known as an "umbrella review" on lanthanide‐based single‐molecule magnets (4f‐SMM). As a preamble, various bibliographic search techniques and AI‐based tools for bibliographic search, indexing, and summarization are proposed and commented. Then, the main milestones in 4f‐SMM are identified. In the core of the paper, books, book articles, and reviews dealing with 4f‐SMM are contextualized and classified by subtopics. This article is therefore proposed as a gateway to the 4f‐SMM field.
