Proceeding in the usual manner, we find for the susceptibility above the

**Curie****point**1 g1 – f as for case A, with the difference that now f – g 1 does not vanish atthe

**Curie point**. At the**Curie point**, but on the low temperature side, we find (8.20)...

The susceptibility above the

**Curie point**is deduced by postulating that the Curielaw (9.15) holds if we take as the magnetic field the sum of the applied field H

and the Weiss field He. Then M C 5.4 — — — » (15.4) H + XM T Or M C (15.5) T II
