Experimentally the low field susceptibility shows a sharp cusp at a low temperature Tg, indicating that the local spins are frozen randomly in direction. On the other hand, the specific heat does not exhibit any evidence for a phase transition at Tg, and no long-range order has been observed by neutron scattering measurement. These features have been observed widely in dilute magnetic alloys in which the long-range RKKY interaction dominates and also in insulating compounds in which the nearest-neighbor exchange interaction does.
