摘要：

We investigate two successive hierarchized phase segregations in La5/8-yPryCa3/8MnO3, which generate ferromagnetic metallic volumes (V1(FM) and V2(FM)) having different physical origins, stabilities, and parent electronic phases. The singular percolative transition around T-C2 approximate to 100 K is due to a second electronic phase separation (PS), which is specific to the charge-order insulating regions segregated at the first PS process. These findings shed new light on the metastability, atypical dynamics, the nonvolatile magnetoresistance, or the supercooling glass transition in this complex magnetic system.
