N2 - Magnetic susceptibility and high-field magnetization measurements are presented for amorphous Zr40Cu60-xMx (M denoting Fe, Mn, Gd, and Tb) and Nb50Ni50-xFex, with x ranging from zero to about ten. The alloys for M=Gd, Tb, and Fe develop low-temperature ordered states that are characterized as spin glass like, whereas the Mn alloy exhibits no evidence of order down to 1.3 K. The magnetic properties of these alloys are discussed in terms of local random anisotropy, fluctuations in the interimpurity exchange interactions, extremely short electron-mean-free paths, antiferromagnetic interactions between the localized moments and the conduction electrons, and moment instabilities.
