FIG. 1.

(Color online) Exemplified synchrotron x-ray diffraction patterns of Ce75− x Al25+ x (x = 0, 10, and 15 at. %) and La75Al25 metallic glasses.

Image of FIG. 2.
FIG. 2.

(Color online) (a) The resistances as a function of temperature for Ce75− x Al25+ x (x = 0, 10, and 15 at. %) and La75Al25 metallic glasses without magnetic fields. The inset shows the linear logarithmic temperature dependence of resistances of Ce-based metallic glasses at low temperature. (b) The comparison of the resistance of Ce75− x Al25+ x (x = 0, 10, and 15 at. %) metallic glasses as a function of temperature with magnetic field H = 6 T (open circle) and without magnetic field H = 0 (solid circle).

FIG. 3.

(Color online) The magnetoresistances of Ce75− x Al25+ x (x = 0, 10, and 15 at. %) metallic glasses at 2 K. The inset shows the magnetoresistance of the Ce65Al35 metallic glass at 2 K alone, for clarity.

Image of FIG. 4.
FIG. 4.

(Color online) (a) Magnetization curves at a field of 1 T (10 000 Oe) for Ce75Al25 and Ce65Al35 metallic glasses. The inset shows the M–H hysteresis loops of both of the Ce75Al25 and Ce60Al40 metallic glasses at 5 K. (b) Temperature dependence of the inverse susceptibility, χ, of both Ce75Al25 and Ce60Al40 metallic glasses. At high temperature (above 120 K) and low temperature (below 30 K in the inset), χ evidently follows a Curie-Weiss behavior. The solid lines represent the fits 1/χ = (T − θ)/C.

Image of FIG. 5.
FIG. 5.

(Color online) Ce 2p3d RIXS spectra for the Ce75Al25 metallic glass at 300 K as a function of the transfer energy (E 1  − E 2). The RIXS maximum amplitude is normalized to be unity and all spectra are offset for clarity on the left scale. The incident energies, E 1, are indicated on each pattern, relative to the edge position E 0 (5.7233 keV). The dashed lines indicate the RIXS components attributed to the mainly 4f 2 and 4f 1 final states.
