Magnetic and transport properties of Ce2CuSi3 single crystal

Magnetic susceptibility and magnetization of Ce2CuSi3, single crystal show strong anisotropy. it is revealed that the magnetic susceptibility exhibits a maximum at 2K only along the hexagonal c-axis at low magnetic fields. The anisotropic magnetic properties are explained by crystalline electric field effect. The analysis of the magnetization curves indicates that magnetic ordering does not occur down to 1.8 K. Electrical resistivity behaves as a typical Kondo-lattice system with the crystalline electric field effect. (C) 3000 Elsevier Science B.V. Ail rights reserved.
