The structural, magnetic and magnetocaloric properties of the resulting materials are presented. The HEAs successfully is produced by the arc melting with suction casting method. The crystal structures are characterised through multiphase Rietveld refinement of X-ray diffraction data. The structure of the HEAs was found to be the body centred cubic (bcc). In the magnetic measurements, the ferromagnetic to paramagnetic transition was obtained in the range of 300–400 K. With the employed suction casting method; the Fe26.7Ni26.7Ga15.6Mn20Si11 HEA shows the best magnetocaloric properties as 1.59 Jkg−1K−1 maximum magnetic entropy change (0–2 T) and 75.68 Jkg-1 refrigeration capacity after the annealing process.eninfo:eu-repo/semantics/closedAccessHigh entropy alloys (HEAs)Magnetic materialsSoft magnetic propertiesMagnetocaloric effect (MCE)Solid-solution phaseMagnetic refrigerantsRoom-temperatureMechanical-propertiesBehaviorCOMicrostructureStabilityNICrystal structureEntropyGallium alloysHigh-entropy alloysIron alloysMagnetic materialsManganese alloysRare earthsRietveld refinementSilicon alloysSoft magnetic materialsMagnetic entropy changeMagnetocaloric propertiesParamagnetic transitionRefrigeration capacityResulting materialsSoft magnetic propertiesX-ray diffraction dataMaterials sciencePhysicsArticle0004969963000042-s2.0-850728789861822201Materials science, multidisciplinaryPhysics, appliedHigh-entropy Alloys; Laves Phases; Entropy
