Description
In the quest of controlling materials’ properties on demand, light presents a promising avenue due to its ability to provide ultrafast control and induce phases of matter that are otherwise inaccessible through traditional adiabatic means. This unlocks states exhibiting tailored emergent properties, named hidden phases. Here, we demonstrate how to reach in the same system two distinct metastable structural hidden phases associated with different electronic properties. This manipulation is made possible by harnessing the strongly correlated nature of magnetite and employing two specific photon energies to photoexcite the system. This study breaks ground for an approach to control matter at ultrafast timescale using tailored photon pulses.
