The most pronounced β-relaxation was found in the Y-based binary metallic glasses(MGs). The correlation betweenβ-relaxation and local atomic structure was studied. The dynamic mechanical measurements were performe...

We investigate the total intensity fluctuation spectrum of the two-longitudinal- mode Nd:YVO4microchip laser(ML).We find that low-frequency relaxation oscillation(RO) peaks still appear in the total intensity flu...

In this paper the relationship between the surface relaxations and the electron density distributions of surface states of Cu(100), Cu(110), and Cu(111) surfaces is obtained by first-principles calculations. The...
