Abstract

We investigated the magnetic and electronic properties of an antiferromagnet and pressure-induced superconductor CePd5Al2 by measuring the magnetization and de Haas-van Alphen effect, together with the electrical resistivity under pressure and magnetic field. Magnetic measurements including the high field magnetization at 1.3 K reveal several magnetic transitions and quite complex magnetic phase diagram of this compound. Electrical resistivity measurements have been performed using diamond anvil cell up to 12 GPa for the magnetic fields H ∥ [0 0 1] and [1 0 0]. The upper critical field in superconductivity is anisotropic between H ∥ [0 0 1] and [1 0 0] in the tetragonal structure, reflecting the quasi-two dimensional electronic state.
