Abstract
From linear birefringence measurements the authors have deduced the temperature dependence of the magnetic energy, related to the short-range order, in the quasi-1D Ising S=1/2 diluted antiferromagnet CsCo1-xMgxCl3. Considering the limits of the exact theoretical model to interpret the temperature dependence of the magnetic energy of the pure CsCoCl3 crystal, the experimental data for diluted samples (x=0.08 and x=0.114) agrees with calculations. NMR was used to study the long-range order. As expected for quasi-1D Ising systems the Neel temperature is highly sensitive to the dilution and varies linearly with it: (1/TN(x=0))/(dTN(x)/dx)=-10.35.Keywords
