In situ synchrotron small angle scattering experiments on the magnetic bulk amorphous alloy Nd60Al10Fe20Co10 are reported. The alloy appears to follow very different decomposition processes at different temperatures. Different decomposition mechanisms at the low and high temperatures are proposed based on our scattering data.
