Thermal expansion of the quasi two-dimensional magnetic layered compound BaNi${}_2$V${}_2$O${}_8$ under magnetic fields along c-axis

W. Knafo, C. Meingast, K. Grube +5

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 i…
