AC susceptibility of a novel 2D rare-earth boron-cluster spin glass system

The AC susceptibility of a novel rare-earth boron-cluster-containing spin glass was measured. REB 17 CN, REB 22 C 2 N, and REB 28.5 C 4 (RE = Er, Ho) are a newly discovered class of crystalline, non-doped spin glass system in which the rare-earth atoms have a two-dimensional configuration. Well defined maxima in the in-phase linear AC susceptibility of HoB 22 C 2 N were observed with corresponding behaviour of the out-of-phase susceptibility as expected for a spin glass. It was found that the dynamical scaling theory of a 3D system, τ/τ 0 = [(T - T 0 )/T] -zv , could not describe the data well. More reasonable parameters could be extracted in terms of a generalized Arrhenius law In(τ max /τ 0 ) a T -2 f which describes 2D spin glass systems. This result is in agreement with the previous studies which indicate the two-dimensionality of this system.
