Why is AFM type II of an fcc system geometrically frustrated ?
I guess you have something else in mind, because the type II AFM is clearly 
defined, isn't it.

Betreff: Re: [Wien] Type II AFM MnO

Just a comment;
The structure that you put as MnO is the usual rock salt structure, where the 
Mn form a FCC structure, you can arrange an antiferromagnetic structure by 
alternating Mg up and Mg dn in the 111 direction, which is what you put in the 
structure.
But the FCC structure with antiferromagnetic leads to what is called a 
geometrically frustrated system.
