(color online) (a) Specific heat of κ-(ET)₂Cu₂(CN)₃ under different fields up to 8 T in comparison with those of other ET-based salts. From Ref. [66]. (b) Low-temperature thermal conductivity κ of κ-(ET)₂Cu₂(CN)₃ (samples A and B). Sample A was investigated under a 10-T field applied along the c axis. From Ref. [67].
