description

Abstract We report on the specific heat data of the ordered bimetallic compounds CoCo(CoEDTA) 2 ·4H 2 O and CoCo(NiEDTA) 2 ·4H 2 O in the temperature range 1.5−15 K. The magnetic specific heat is analyzed from an Ising model that assumes three different magnetic sublattices exchange-coupled by two distinct magnetic interactions, as well as local anisotropies on tetrahedral Co and octahedral Ni sites.
