英文摘要 | Specific heat, magnetic susceptibility and magnetization of Co(N-3)(2)(bpg)[(CH3)(2)(NCOH)](4/3), representing S = 3/2 kagome system are reported. Long-range ordering at 16 K was revealed, however, at lower temperatures slow spin dynamics is still found. The analysis of alternating susceptibility suggests the onset of glassy state. The study of the time dependence of magnetization revealed the existence of more relaxation channels with pronounced different relaxation times. The observed behaviour is consistent with the formation of topological spin glass in which relaxation is governed by both spin and chiral degrees of freedom.; Physics, Multidisciplinary; SCI(E); CPCI-S(ISTP); 0 |
