Abstract: Magnetic properties of CePtAl single crystals with orthorhombic TiNiSn-type crystal structure were investigated for each axis by measurements of magnetic susceptibility, high-field magnetization up to 30 T and magnetoresistance up to 10 T. The pronounced anisotropy observed indicates that magnetism in CePtAl is dominated by a ferromagnetic component along the magnetically easy a-axis and that the magnetically hard axis changes from the c-axis (T > 39 K) to the b-axis (T
