Abstract Topological magnetic textures (TMTs) such as skyrmions, merons, and vortices are promising for next‐generation spintronic technology. Here, the prospect of TMTs in cooling technology is explored, influence on magnetocaloric effect (MCE) typical Janus monolayers (symmetry‐broken VSi 2 N 4 derivatives) that exhibit prominent Dzyaloshinskii–Moriya interaction (DMI) specifically elaborated. It found P , As NAs 3 allow versatile including bimerons, meron pairs skyrmions. Skyrmions bimerons demonstrated to remain stable up 100 K. Under external fields, either experience shrinkage or a significant magnetization reversal. This results TMTs‐mediated MCE driven by topological magnetic‐to‐ferromagnetic phase transition, which intrinsically differs from conventional paramagnetic‐to‐ferromagnetic transition. The revealed benefit combination pseudo‐first‐order second‐order transition thus broader operating temperature range. These findings offer an in‐depth understanding role can inspire nanoscale 2D science
