The essential contribution of Heisenberg to the theory of ferromagnetism was in showing
that those effects which had been correlated by means of the formal molecular field …

The collective electron treatment of ferromagnetism (Stoner 1938 a, 1939) is applied to the
magnetic and thermal properties of nickel and nickel-copper alloys. In § 1 a brief description …

Plusieurs rapports généraux ayant paru, récemment sur les diverses méthodes théo-riques
pour aborder le problème du ferromagnétisme, on s' occupe ici seulement de la méthode …

In two previous papers expressions have been obtained for the susceptibility and specific
heat of free electrons in forms appropriate for low and high temperatures. With slight …

A treatment of collective electron ferromagnetism on the basis of FermiDirac statistics was
developed in a previous paper (Stoner 1938 a, referred to as I). The problem considered …

This paper is intended to supplement the review articles published by Stoner in 1948 and
1951, firstly by considering in greater detail the quantum-mechanical and statistical …

A general introduction surveying the problems to be examined in a series of papers is
followed by a detailed treatment of the magnetic behaviour of a large system of electrons …

The most serious defect of the modern theory of metals is the very unsatisfactory manner in
which it takes account of the forces of interaction between the valency electrons of the metal …

With the model proposed in an earlier paper, the temperature variation of the
ferromagnetism of nickel is discussed. By application of Fermi statistics to the electrons in …

The wave function 4 is represented by {k)'kt {~ j~ & 0'(4) where 4o is the vacuum. The sets {k]
and {z] ex-tend over the appropriate regions in reciprocal space. These regions are, in …
