Weak itinerant magnetism as inhibited superconductivity

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

Thep-state pairing idea proposed recently to explain the ferromagnetism of ZrZn2 is described in more detail, and the underlying soft-mode hypothesis is examined in relation with experiments, in particular the discovery of antiferromagnetism in TiBe2. The key result, namely an electron-phonon contribution to the Stoner factor given essentially by the mass enhancement factorλ, is used to explain the behaviour of the Curie pointT m and to predict an isotope effect.p-state superconductivity with a transition temperature determined byλ is predicted in TiBe2 and, above the critical pressure whereT m =0, also in ZrZn2.
