However, such noticeable changes in peak widths with pressure were not observed in Ho3Co. At ambient pressure, peak of -ΔSM(-ΔSMpk) scales with (H/TN)2/3for both the compounds, consistent with the prediction of mean field theory (MFT) for second order magnetic transition. However, deviation from MFT was noticed at high pressures as -ΔSMpkwas found to scale with (H/TN)3/4instead of (H/TN)2/3for both the alloys. Further, normalised -ΔSMcurves for different ΔH and pressures collapse on a single universal curve in both the compounds there
