Magnetic and transport properties of a new cubic compound CeMgZn 2 have been examined by measuring the magnetic susceptibility, the magnetization, the electrical resistivity, and the specific heat. CeMgZn 2 is a Kondo-lattice compound with trivalent Ce ions. The magnetic susceptibility measured at 0.1 T exhibits a shoulder and a cusp at T N1 = 5.4 K and T N2 = 3.1 K, respectively. T N1 and T N2 correspond to the antiferromagnetic-transition temperatures since these temperatures decrease with increasing magnetic field. The large value of the paramagnetic Curie temperature divided by T N1 (13.5) implies that T N1 is suppressed by geometrical frustration on a face-centered cubic Ce sublattice. The geometrical frustration may also be responsible for the appearance of many magnetic phases in magnetic fields.
