Description

Moessbauer effect, d.c. magnetisation and a.c. susceptibility measurements in disordered spinel ferrite Ga0.8Fe0.2NiCrO4 (0.3 ≤ T ≤ 300 K, -12 ≤ H (external field) ≤ 12 kOe) show it to be a cluster spin glass where Gabay - Toulouse phase diagram transitions occur not for individual spins but for groups of correlated spins (clusters) whose effective spin's transverse and longitudinal components successively freeze. (orig.)
