Abstract :
Although the need for a theory of ferrimagnetism has existed for over 2,000 years, this has only become obvious for about a decade. The importance of Neel´s suggestion that possibly within a given domain not all of the magnetic ions have their magnetic moments arranged parallel to each other is discussed at some length, and the hope is expressed that in the future a ferrite may be obtained which is ferromagnetic.
