The magnetic moment of a gadolinium atom is 7.95 Bohr magnetons. Gadolinium crystals are packed into a face-centered cubic lattice with a period of 3.2 A. Determine the saturation magnetization. Consider that in a face-centered packing the unit cell includes four atoms (see Problem 20.15). 20.15. What is the number of atoms in the unit cell of a face-centered cubic lattice?
