    • Abstract


      The Heisenberg model with competing interactions is studied within a mean field, effective medium approach. The phase diagram indicates the existence of a mixed or randomly canted phase just beyond the spin glass regime. Experimental evidence of such a phase in alloys like FeCr is studied.
