A series of Mn 3 Ga 1− x Ge x C (x= 0, 0.1, 0.2) compounds were prepared by solid state reaction, and their magnetic properties, phase transitions, and magnetocaloric effect were investigated. All samples, after becoming ferromagnetic below Curie temperature T c, undergo a first-order ferromagnetic–antiferromagnetic transition at T t at low temperature, giving rise to conventional and inverse magnetocaloric effect. T t increases while T c shows a decrease with the increase of Ge content. Isothermal magnetization curves around T t are strongly history-dependent, which may result in spurious peak in the magnetic field induced entropy change (Δ S M). The magnetothermal properties near T t, compared with those near T c, are of larger Δ S M, but have larger magnetic hysteresis and smaller refrigerant capacity.
