Magnetization, magnetic susceptibility, electrical resistivity, thermal expansion, specific heat and magnetocrystalline anisotropy measurements have been made on Gd_75Sc_25 single crystals Low isofield a-c susceptibility data for the c-axis sample exhibit the existence of antiferromagnetism, which rs suppressed ferromagnetically by the applied field of 30 Oe. Electrical resistivity, thermal expansion and specific heat data show an anomaly at T_N. Magnetocrystalline anisotropy measurements show that the easy direction changes from the basal plane to the c-axis at 87 K with increasmg temperature.
