Magnetic Anisotropy in DyNi2B2C system

To figure out the magnetic and transport anisotropy in DyNi$_{2}$B$_{2}$C which have superconducting critical temperature T$_{c}$ lower than the antiferromagnetic Neel temperature T$_{N}$ among RNi$_{2}$B$_{2}$C (R$=$ rare earth elements) compounds, we have measured the static magnetization curves M(H,T) with the applied magnetic fields parallel and perpendicular to the crystallographic c-axis at various temperatures and applied magnetic fields. We have observed several magnetic transitions only for the applied magnetic field perpendicular to the c-axis and such magnetic transitions have shift sensitively to the higher temperature regions. We compared our results with the Dy$^{+3}$ magnetic sublattice structure previously reported from neutron scattering experiments
