    The XRD pattern of HoNi/HoNi2 composite along with Rietveld refinement using FULLPROF program. Inset shows the BSE image of HoNi/HoNi2 composite.
    The T dependence of M (left-scale) and 1/χ (H/M, right-scale) at H = 10 kOe for HoNi/HoNi2 composite. The inset illustrates M–T curves measured at H = 2 kOe in ZFC and FC modes as well as d M/d T–T curve for HoNi/HoNi2 composite.
    (a) The M–H curves under H up to 70 kOe for HoNi/HoNi2 composite. (b) The corresponding Arrott-plots (M2 vs. H/M).
    The –ΔSM–T curves at different ΔH for HoNi/HoNi2 composite compound. Inset illustrates the RC1, RC2, and RC3 values at different ΔH for HoNi/HoNi2 composite.
    • Table 1. The TM, ΔSMmax, and RC1 for HoNi/HoNi2 composite and recently reported table-like MCE materials, as well as some other MR materials under the field change of 0–50 kOe.
