“…For the spin-flip scattering, the peak at Q h ≈ -0.27 is observed with the same intensity and lineshape in the σ +− z and σ −+ z channels. It is ascribed to a spin-wave mode from the facts that (i) the direction of fluctuations is found to be perpendicular to the ordered magnetic moments and (ii) its peak position is in agreement with the established magnon dispersion of MnFe 4 Si 3 [3]. The leakage of the magnon scattering from σ αβ z (α = β) to σ αα z due to finite polarization is barely seen above the background level for both channels.…”

“…Interest for the magnetocaloric effect has been increasing in the last decades in view of applications for room temperature refrigeration [1]. Neutron scattering studies can bring important microscopic information on the spin and lattice dynamics of these systems and reveal key ingredients at play in their magneto-thermodynamics properties [2,3,4]. In such context, experiments were performed on the ferromagnetic compound MnFe 4 Si 3 and the importance of short range magnetic correlations as well as their suppression by a modest magnetic field was highlighted [3].…”

A full phonon intensity cancellation is reported in a longitudinal polarized inelastic neutron scattering experiment performed on the magnetocaloric compound MnFe4Si3, a ferromagnet with TCurie ≈ 305 K. The TA[100] phonon polarized along the c-axis measured from the Brillouin zone center G=(0, 0, 2) is observed only in one (σ ++ z ) of the two non-spinflip polarization channels and is absent in the other one (σ −− z ) at low temperatures. This effect disappears at higher temperatures, in the vicinity of TCurie, where the phonon is measured in both channels with nonetheless marked different intensities. The effect is understood as originating from nuclear-magnetic interference between the nuclear one-phonon and the magnetovibrational one-phonon scattering cross-sections. The total cancellation reported is accidental, i.e. does not correspond to a systematic effect, as established by measurements in different Brillouin zones. arXiv:1812.02564v1 [cond-mat.mtrl-sci] 6 Dec 2018 located after the velocity selector and the Heusler analyzer was set at fixed k f =2Å −1 . The sample is the same single crystal as the one used in Ref. [3]. It was placed in a vertical field magnet, the field being along the b-axis of the hexagonal structure and the horizontal scattering plane being thus defined by a * and c * . A magnetic field of 1 T was applied in the paramagnetic state and the sample was field-cooled in order to get a single domain ferromagnetic sample. Hence, the polarization at the sample position is kept along the magnetic field which defines the z-axis. Two Mezei spin flippers were used before and after the sample in order to measure the four possible polarized neutron cross-sections σ αβ z ={σ ++

“…Initially investigated in the 60s and 70s [1][2][3][4], transition metal-based compounds deriving from Mn 5−x Fe x Si 3 are currently receiving a renewed interest for their rich magnetic properties and for their potential use in magnetocaloric applications [5][6][7][8][9][10][11]. Mn 5−x Fe x Si 3 compounds were originally believed to crystallize in the hexagonal structure with Mn and Fe distributed on 4d and 6g sites, and Si metalloid atoms on 6g sites with different coordinates.…”

The transition-metal based alloy MnFe 4 Si 3 not only is a potential candidate for room temperature magnetocaloric applications, but also shows a large magnetic anisotropy forming an interesting case study in the search for rare-earth free permanent magnets. However, former polycrystalline and single crystal studies led to major disagreements about the order of the magnetic transition and the magnetocrystalline anisotropy scheme, which are two essential points for the understanding of this alloy. Here, magnetic, magnetocaloric properties and the magnetic anisotropy of MnFe 4 Si 3 (Mn~0 .86 Fe~4 .24 Si~2 .90) are investigated on a high quality single crystal grown by flux method, and compared to polycrystalline materials. Using the recently proposed criterion of field dependence of the magnetocaloric effect, we show that the ferromagnetic transition is more likely to be of second order, which is fully compatible with the absence of thermal hysteresis at the ferromagnetic transition in the present MnFe 4 Si 3 crystal. The c axis is confirmed to be the hard magnetic axis, both in single crystal and polycrystalline MnFe 4 Si 3 , and a large, dominant, K 1 anisotropy constant (~−2.5 MJ m −3) is found at low 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.
