【 摘 要 】

The quasi two-dimensional magnetic BaNi2V2O8 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 10T. Positive and negative pressure dependencies of T-N, respectively, are inferred from the thermal expansion alpha(T) for pressures applied along the a- and c-axes. (c) 2006 Elsevier B.V.
