Magnetic properties and B–T phase diagram in the heavy-fermion superconductor CePt3Si

Abstract: Magnetic and superconducting properties have been investigated on a single crystal of CePt3Si which is the recently discovered heavy-fermion superconductor. The effect of magnetic field on the antiferromagnetic transition temperature was studied by the iso-field thermal expansion coefficient. From these results, together with the results of the electrical resistivity under magnetic fields, magnetostriction and magnetization measurements, we have constructed the magnetic and superconducting phase diagrams for and [001].
