IS THERE A METAMAGNETIC PHASE TRANSITION IN Pd?

Electronic structure calculations for Pd in external magnetic fields are presented. The external magnetic field is included self consistently by adding the Zeeman term to the variational step. Thereby the Zeeman splitting interacts with the exchange — correlation potential and the spin — orbit coupling. As Pd is on the border of ferromagnetism, calculations of the magnetization as a function of applied field are presented for a variety of exchange — correlation potentials and orbital effects, as well as for expanded crystals. At the experimental lattice constant no phase transition is found.
