H. Gamariseale et al., THE PECULIAR LOW-TEMPERATURE MAGNETIC-BEHAVIOR OF DYCO2FEGA2, Journal of magnetism and magnetic materials, 144, 1995, pp. 937-938
The magnetisation with respect to temperature and field of DyCo2FeGa2
has been measured by ac and de techniques. The compound is ferrimagnet
ic with T-C = 393 K and exhibits two maxima, a sharp one at 40 K and a
broad one centred at 200 K for the SQUID and around 140 K for the VSM
and ac measurements. Below the broad maximum, irreversibility is obse
rved.
