Abstract

Cu_cCo_1-cCl₂-FeCl₃ graphite bi-intercalation compounds (GBIC's) have a c-axis stacking sequence of -G-I₁-G-I₂-G-I₁-G-I₂-G- (G = graphite layer, I₁ = Cu_cCo_1-cCl₂ layer, and I₂ = FeCl₃ layer). These compounds undergo magnetic phase transitions at T_h, T_cu, T_cl, T_SG, and T_RSG (T_h>T_cl>T_RSG≈T_SG), depending on the Cu concentration. The phase transition at T_h is related to a helical spin order. The phase transitions at T_cu and T_cl are associated with a spin order of Cu_cCo_1-cCl₂ layers. The re-entrant spin glass phase below T_RSG for c≤0.4 and the spin glass phase below T_SG for c≥0.5 are due to the spin frustration effect occurring in FeCl₃ layers. The nature of these phases has been studied using SQUID DC magnetization and SQUID AC magnetic susceptibility.
