The magnetocaloric (MC) and magnetic phase transition (MPT) properties in various types of rare earth (RE)-based magnetic materials have been intensively investigated recently, which are aimed at developing suitable MC materials for low-temperature cooling applications and better elucidating their inherent physical properties. We herein provide a combined experimental and theoretical investigation into two new light REbased magnetic materials, namely, PrZnSi and NdZnSi compounds, regarding their structural, magnetic, MPT, and low-temperature MC properties. Both of these compounds crystallize in an AlB 2 -type hexagonal structure with a symmetry of the crystallographic space group P6/mmm and reveal a typical second-order-type MPT with ordering temperatures (T C ) at approximately 13.5 and 18.5 K for PrZnSi and NdZnSi compounds, respectively. Moreover, they all exhibit large reversible low-temperature MC effects and remarkable performances, which are identified by the parameters of maximum magnetic entropy changes, relative cooling power, and temperature-averaged entropy change (temperature lift 5 K). The deduced values of these MC parameters under a magnetic field change of 0−7 T reach 16.3 J/kgK, 294.46 J/kg, and 15.79 J/kgK for PrZnSi and 15.4 J/kgK, 284.84 J/kg, and 14.95 J/kgK for NdZnSi, respectively, which are evidently better than those of most updated light RE-based magnetic materials with remarkable low-temperature MC performances, indicating that PrZnSi and NdZnSi compounds hold potentials for practical cooling applications.

The magnetocaloric (MC) properties in many rare-earth (RE)-containing magnetic solids have been intensively investigated, which are aimed to develop suitable candidates for cryogenic magnetic cooling applications and to better understand their intrinsic magnetic characters. We herein fabricated the RE-rich RE6Ni2.3In0.7 (RE = Ho, Er, and Tm) compounds and investigated their structural, magnetic, and MC properties by experimental determination and theoretical calculations. All of these RE6Ni2.3In0.7 compounds crystallize in an Ho6Co2Ga-type structure with an orthogonal Immm space group and order magnetically around the temperatures of 10.6 and 33.0 K for Ho6Ni2.3In0.7, 11.0 K for Er6Ni2.3In0.7, and 7.6 K for Tm6Ni2.3In0.7, respectively. Large cryogenic reversible MC effects were observed in these RE6Ni2.3In0.7 compounds. Moreover, their MC parameters of maximum magnetic entropy changes, relative cooling powers, and temperature-averaged magnetic entropy change are comparable with those of some recently updated cryogenic MC materials.
