It is possible to express the magnetic susceptibility χm in several different units. For the discussion of this chapter, χm was used to designate the volume susceptibility in SI units, that is, the quantity that gives the magnetization per unit volume (m3) of material when multiplied by H. The mass susceptibility χm (kg) yields the magnetic moment (or magnetization) per kilogram of material when multiplied by H; and, similarly, the atomic susceptibility χm(a) gives the magnetization per kilogram-mole. The latter two quantities are related to χm through the relationships
χm = χm(kg) × mass density (in kg/m3)
χm(a) = χm(kg) × atomic weight (in kg)]
When using the cgs-emu system, comparable parameters exist, which may be designated by χ′m, χ′m(g), and χ′m(a); the χm and χ′m are related in accordance with Table 20.1. From Table 20.2, χm for silver is -2.38 × 10-5; convert this value into the other five susceptibilities.
