The crystal structure of new hexagonal MgZn2-type {Ho, Tm}FeGa compounds (space group P63/mmc, N 194, hP12) has been established using powder X-ray diffraction studies. The magnetic properties of polycrystalline MgZn2-type ErFeGa compound have been studied using bulk magnetization data. ErFeGa exhibits ferromagnetic ordering at TC = 77K and field sensitive antiferromagnetic-like ordering at Tm ~ 58K in field of 100Oe and Tm ~ 10K in field of 5kOe. The paramagnetic susceptibility follows Curie-Weiss law with effective paramagnetic moment per formula unit (Meff/fu) of 9.59μB and paramagnetic Weiss temperature (ΘP) of 27K.At 2K, ErFeGa exhibits hard magnetic properties with remanent magnetization per formula unit (Mres/fu) of 3.7μB, coercive field (Hcoer) of 8.2kOe and critical field (Hcrit) of ~9.6kOe.The magnetocaloric effect of ErFeGa has been calculated in terms of isothermal magnetic entropy change (ΔSm) and maximum ΔSm values are −5.5J/kgK for a field change of 0–50kOe (relative cooling power RCP50kOe ~ 410J/kg), −13.0J/kgK for a field change of 0–140kOe (RCP140kOe ~ 1230J/kg) at 70K and +1.7J/kgK for a field change of 0–10kOe at 10K (RCP10kOe ~ 34J/kg).
