Ultrafast optical excitations allow creating new metastable and hidden states in quantum materials. However, the fundamental material properties required to support emergent order are largely unknown. Here we show for two colossal magnetoresistive (CMR) manganites that electronic phase separation (EPS) strongly favors non-thermal behavior exploit this stabilize an optically-induced conducting state. Our results shed light on role of EPS control CMR provide guidance design materials can exhibit non-equilibrium matter.
