Magnetic phase diagrams of Ho1-xDyxNi2B2C

초록

We performed the magnetization measurement on Ho1-xDyxNi2B2C single crystals (x = 0.1, 0.2, 0.3, 0.4, and 0.6) with magnetic field applied perpendicular and parallel to the c-axis. But only for the magnetic field perpendicular to the c-axis, the increase of Dy3+ concentration affects the magnetically ordered states of HoNi2B2C compound and makes the phase diagram more complicated. The antiferromagnetic ordering state attributed to Dy3+ sublattice starts to appear from a case of x = 0.2 and finally the magnetic phase diagram becomes analogous to that of DyNi2B2C as x is increased which is consistent with the neutron scattering result.
