中文摘要	Multiple spin-glass-like (SGL) behaviors have been observed in a Pr60Al10Ni10Cu16Fe4 bulk metallic glass (BMG). Various measurements are carried out to confirm the coexistence of a reentrant-SGL ordering at 14 K, and two cluster-SGL transitions around 6 K and 280 K. The unusual multiple SGL behaviors are ascribed to the couple between the magnetic nanoclusters and the amorphous matrix. The combination of the intrinsic inhomogeneity, spontaneous nanoconfinement and magnetic completing in the BMG leads to the three qualitatively distinct SGL transitions with unique characteristics such as the elevated freezing temperature close to room temperature in cluster SGL. Comparing with the most spin glass (SG) materials with only one SG phase, the Pr-based BMG with multiple SGL phases provides an ideal prototype to fill up the gap for the unknown interactions between two or more SGs, which is of significance to expand current understanding of both SG and more complex systems.
