Query: Magnetism of sigma-phase Fe-Mo alloys: its revealing and
  characterization   A low-temperature magnetism was revealed in a series of sigma-Fe(100-x)Mo(x)
alloys (x=45-53). Its characterization has been done using vibrating sample
magnetometry, M\"ossbauer spectroscopy, and ac magnetic susceptibility. The
magnetic ordering temperature was determined to lie in the range of 46 K for
x=45 and 22K for x=53, and the ground magnetic state was found to be typical of
a spin-glass.
