Abstract: | We report here our magnetic study on amorphous GdxY1?x alloys with x = 0.17 and 0.70. The alloy with x = 0.17 is paramagnetic down to 4.2 K. For x = 0.70, magnetization shows a peak in low magnetic fields (H < 0.3 T). Magnetic saturation is difficult to obtain even for fields up to 15 T. An extrapolated value gives a moment of . Tc is about 70 K. This led us to the conclusion that ferromagnetic and antiferromagnetic clusters are present in this alloy. The results are discussed by comparing them with crystalline Gd-Y alloys and amorphous Gd-Al, Gd-Au, etc. The effect of Y seems to be specific. |
