Abstract

The quasi two-dimensional magnetic BaNi $_{2}$ V $_{2}$ O $_{8}$ is studied by using high-resolution thermal expansion in magnetic fields up to 10 T applied along the c-axis. A slight increase of about 1 % of the three-dimensional antiferromagnetic ordering temperature $T_{N}$ is observed at 10 T. Positive and negative pressure dependencies of $T_{N}$ , respectively, are inferred from the thermal expansion $α (T)$ for pressures applied along the $a$ - and $c$ -axes.
