Garnets molecular field

Al mard (5) has applied the method to the ferrimagnetic garnets, where the ionic distributions are known. He includes, to first order, the temperature dependence of the molecular field constants, n = no(l + yT), that was first formulated by N6el (472). The coefficient 7 10 4 is proportional to the coefficient of thermal ex-...

The Neel theory of antiferromagnetism (a molecular field treatment for three sublattices of the garnet structure), as applied to ferrimagnetism (Neel, 1948), shows that the fields acting at a-, d-, and c-sites, respectively, are...
