Calculate the saturation magnetization in A/m for MFe2O4 given that each MFE2O4 cubic unit cell contains 8 M2+ and 16 Fe3+ ions, and that the unit cell edge length is 0.89nm. You may assume that each M2+ has a net 3 unbalanced spins.
Imagine a unit cell that consists of corner-centered atoms "A", body-centered atom "B", face-centered atoms "C", and edge-centered atoms "D". This would mean that the total parts of "A" would add to Blank 1 atom(s), the total parts of "B" would add to Blank 2 atom(s), the total parts of "C" would add to Blank 3 atom(s), and the total parts of "D" would add to Blank 4 atom(s). Assume that a crystal structure is made up...
