“…Abundant forms of magnetic ordering exist in rare-earth-based compounds because of various magnetic couplings such as Ruderman–Kittel–Kasuya–Yosida (RKKY) indirect interaction, magnetocrystalline anisotropy, and magnetic quadrupole moment interaction . As a result, superlattice magnetic ordering as well as incommensurate magnetic ordering are common, and multitudinous unconventional magnetic structures have been observed in rare-earth compounds such as transverse spin density wave (TSDW)/longitudinal spin density wave (LSDW), sine-modulated, spiral, cycloid, and conical magnetic structures . The specific form of magnetic ordering plays an important role in the physical properties of rare-earth-based magnetic materials.…”

We present herein a systematic study of a polycrystalline magnetocaloric compound ErFe 2 Si 2 . It exhibits a transition from the antiferromagnetic to the paramagnetic phase around 3.0 K according to magnetic and heat capacity measurements. Neutron powder diffraction revealed that ErFe 2 Si 2 possesses a superlattice magnetic structure with a propagation vector of (0, 0, 0.5). The superlattice magnetic structure can be modeled by a transverse spin density wave (cosine-modulated) or a spiral type, which cannot be distinguished solely by neutron powder diffraction (NPD) pattern fitting. The stability of different types of magnetic structures was also investigated by first-principles calculations. The ErFe 2 Si 2 compound shows a giant magnetocaloric effect with a maximal negative magnetic entropy change and an adiabatic temperature change of 11.5 J/kg K and 5.7 K, respectively, under the field change of 0−1 T. The large low-field magnetocaloric effect is related to its low critical field of metamagnetic transition and its low quasi-saturation magnetic field. The excellent performance of ErFe 2 Si 2 makes this compound a potential magnetocaloric material for applications at liquid helium temperatures.

Solid‐state caloric effects as intrinsic thermal responses to different physical external stimuli (magnetic‐, uniaxial stress‐, pressure‐, and electric‐fields) can achieve a higher energy efficiency compared with traditional gas compression techniques. Among these effects, magnetocaloric energy conversion is regarded as the best available alternative and has been exploited extensively for promising application scenarios in the last decades. This review systematically introduces the magnetocaloric effect and its applications, and summarizes the corresponding representative magnetocaloric materials, as well as important progress in recent years. Specifically, the review focuses on some key understandings of the magnetocaloric effect by utilizing state‐of‐the‐art technical tools such as synchrotron X‐ray, neutron scattering, muon spin spectroscopy, positron annihilation spectroscopy, high magnetic fields, etc., and highlights their importance toward advanced materials design and development. An overview of the basic principles and applications of these advanced techniques on magnetocaloric materials is provided. Finally, the challenges and perspectives on further developments in this field are discussed. Further in‐depth understanding and manufacturing technology advancement combined with fast‐developed artificial intelligence and machine learning are expected to advance the magnetocaloric energy conversion technology closer to real applications.
