摘要: CsCoCl 3 containing various amount of Mg ++ or Zn ions have been studied by elastic neutron diffraction and magnetic susceptibility measurements. With increasing impurity concentration, T N1 decreases gradually, whereas N2 could not be found down to 1.6 K even in the crystal with 0.2% impurity. The observed phenomena were interpreted terms random field due which destroys long range ordering. One third chain segments odd number Co remains paramagnetic below frozen antiferromagnetic lattice at about irrespective composition. interchain interaction was evaluated from freezing temperature 1.4 K. present results afford another evidence for distinguished spin frustration .
