Gadolinium is a ferromagnetic metal below its Curie temperature of 292 K. When fully magnetized at 260 K it has a saturation magnetization of 1.7 106 A/m . The density and atomic weight of Gd are 7.90 g/cm3 and 157.25 g/mol, respectively. Calculate the effective number of Bohr magnetons each Gd atom contributes to overall magnetization for a fully magnetized sample.
