Abstract

We have grown a CeAu₂Si₂ single crystal and measured the magnetization, specific heat and electrical resistivity as functions of magnetic field and temperature. The obtained results are interpreted in terms of antiferromagnetic (AF) ordering of Ce magnetic moments below the Néel temperature T_N = 4K. At temperatures below T_N we observe a metamagnetic transition from AF to ferromagnetic state in magnetic field applied along the c-axis. The strong uniaxial magnetocrystalline anisotropy has been found both in AF as well as in the paramagnetic state.
