In this study, Zr successfully substituted for Er in Er 6– x Zr x MnSb 2 ( x = 0, 0.5, 1, 1.5) of the Fe 2 P type, with comprehensive characterizations on crystal structure, electronic structure and magnetic properties. According to synchrotron powder X-ray diffraction data analysis and density functional theory calculation, Zr is not randomly but preferentially occupies during the doping process and results in weaker magnetic exchange interactions and depressed ordering temperatures. The electronic structure data show that the doping of Zr can weaken interaction between Er and Mn atoms. Owing to multiple transitions, the Er 6– x Zr x MnSb 2 ( x = 0, 0.5, 1, 1.5) exhibit table-like magnetocaloric effect. Er 6 MnSb 2 displays wide δ T FWHM (full width at half maximum of the magnetic entropy change curve) of 116 K and high relative cooling power of 388.62 J/kg for 3 T. The maximum magnetic entropy change of Er 6– x Zr x MnSb 2 is increasing from 3.81 J/(kg·K) to 7.69 J/(kg·K) with the Zr content up from x = 0 to x = 1.5.
