The number of bohr magnetons per atom for this material is 1.14 when some hypothetical metal that exhibits ferromagnetic behavior and that has 1 simple cubic crystal structure.
Given atomic radius of crystal structure (r) = 0.130nm
saturation flux density of crystal structure = 0.75tesla
We know that n = M/µN = B/µ0µN
n = BVc/µ0µN where Vc is the volume of crystal and B is bohr magneton
n = B(2r)^3/µ0µN = 0.75x(2x0.130x10-9)^3)/(1.25x10-26x9.27x10-24)
n = 13.18x10-30/11.5x10-50 = 1.14x10^20
Hence the number of bohr magnetons per atom for this material is 1.14 .
