At ultrafast timescales, the initial and final states of a first-order metal-insulator transition often coexist forming clusters of the two phases. In this work, we report an unexpected third long-lived intermediate state emerging at the photoinduced first-order metal-insulator transition of La0.325Pr0.3Ca0.375MnO3, known to display submicrometer length-scale phase separation. Using magnetic force microscopy and time-dependent magneto-optical Kerr effect, we determined that the third state is a nanoscale mixture of the competing ferromagnetic metallic and charge-ordered insulating phases, with its own physical properties. This discovery bridges the two different families of colossal magnetoresistant manganites known experimentally and shows for the first time that the associated states predicted by theory can coexist in a single sample.
