Tuning the structural transformation into the temperature region between the Curie temperatures of Hexagonal and Orthorhombic phases can acquire coincident magneto-structural transformation with a large magnetocaloric effect in MnCoGe alloy. However, the investigations about controlling and achieving magneto-structural coupling in MnCoGe-based alloys usually focus on the unidirectional change among the three elements. Here, we report the first-order magneto-structural coupled transformation in Co and Ge bidirectional-regulation MnCoGe alloys. Resultantly, large magnetocaloric effect is obtained around room temperature in both MnCo1-xGe1+xand MnCo1+yGe1-ysystems. The uniform origins of magneto-structural coupling in both systems are explored.
