Consider dysprosium (dy), which is a rare earth metal with a density of 8.54 g cm-3 and atomic mass of 162.50 g mol-1. the isolated atom has the electron structure [xe] 4f106s2. what is the spin magnetic moment in the isolated atom in terms of number of bohr magnetons? if the saturation magnetization of dy near absolute zero of temperature is 2.4 ma m-1, what is the effective number of spins per atom in the ferromagnetic state? how does this compare with the number of spins in the isolated atom?
