An unusual field dependent slow magnetic relaxation and two distinct transitions were observed in a family of new rare earth-transition metal complexes, [Ln (bipy) (H₂O)₄ M(CN)₆] · 1.5 (bipy) · 4H₂O (bipy = 2,2'-bipyridine; Ln = Gd³⁺,Y³⁺; M = Fe ³⁺, Co³⁺). The novel magnetic relaxation, which is quite different from those in normal spin glasses and superparamagnets but very resembles qualitatively those in single-molecule magnet Mn₁₂-Ac even if they possess different structures, might be attributed to the presence of frustration that is incrementally unveiled by the external magnetic field. The two distinct transitions in [GdFe] were presumed from DC and AC susceptibility as well as heat capacity measurements.
