概要
- 論文の詳細を見る
CsCoCl3 containing various amount of Mg" or Zn" Tons have been studied byelastic neutron diffraction and magnetic susceptibility measurements. With increasingimpurity concentration, T.. decreases gradually, whereas T.. could not be founddown to 1 .6 K even in the crystal with O.2% impurity. The observed phenomena wereinterpreted in terms of the random field due to impurity which destroys the long rangeordering. One third of magnetic chain segments with odd number of Co" ions remains paramagnetic even below T., and frozen in the antiferromagnetic lattice atabout 3 K irrespective of composition. The interchain interaction was evaluated fromthe freezing temperature to be 1.4 K. The present results afford another evidence forthe distinguished spin frustration in CsCoCl..
