The effective Bohr magneton number is 2.4–2.8/V and the Weiss temperature is as low as 20 K. They suggest that the bipolaron state does not appear in the host lattice.

The free energy function for the antiferroelectric transition was analyzed in some detail. The role of the intersublattice interaction, which is substantial for giving rise to the antiferroelectric transition, was reconsidered and it is pointed out that a ferroelectric phase with the polarization along the [110] direction may be stabilized when the interaction changes its sign. Also the role of the intrasublattice interaction is mentioned.

The spin dynamics of CoBr 2 can be described by the anisotropic exchange Hamiltonian for S =1/2 with intraplanar exchange constants J 1 =2.01 meV, J 2 =0.019 meV and J 3 =-0.338 meV, interplanar exchange J '=-0.97 meV, and planar anisotropies D 1 =1.14 meV and D '=-0.06 meV. As shown by these numerical values, CoBr 2 has fairly strong XY characters, but the two-dimensionality is definitely poor. We point out, however, that in a planar antiferromagnet, the easy plane type anisotropy should remove the degeneracy of the excitation spectrum for the `in-plane' and the `out-of-plane' correlations, and in fact, these excitations are observed separately in this experiment.","PeriodicalId":269857,"journal":{"name":"Tokyo Sugaku Kaisya Zasshi","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133975884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
