Fmol is the molar volume, Mmol the molar mass and xg = x/p the commonly specified mass susceptibility (p = density). 

The superconducting material YBa2Cus07 weighs 666 g/mole or 222 g/mole Cu. If all the Cu ions were divalent and acted as isolated spins, N in Eq. 4 would be 2.7 x 1021 Cu+2 ions per gram. Hence, the mass susceptibility xg would be 5.6 x 10 6 cms/g at room temperature (295 K) and would increase inversely with decreasing temperature, tripling to 1.7 x 10"5 cms/g at 100 K. 

Fig. 3.18 Reciprocal of paramagnetic mass susceptibility x 1 of Ni 00 - Gax for various compositions near Ni3Ga as a function of T (de Boer et al 1969). Note the behaviour, here ascribed to paramagnons, at compositions 73 and 73.5 at the lowest temperature.

The quantity that is most frequently obtained from experimental measurements of magnetism is the specific (or mass) susceptibility, x- 1 is related to the volume susceptibility through the density, d...

To obtain the mass susceptibility of the pure paramagnetic material, we assume that the volume susceptibility Xs of th solution can be written as a sum of parts. 

Here p is the density of the solution containing w kg of paramagnetic solute per cubic meter and q is th mass susceptibility of the solution without the paramagnetic material. The density of the latter is po so that Xo = Amass oPo and we obtain from Eqs. (10) and (11) the expression... 

Neglecting the third term of Eq. (12), the mass susceptibility of a paramagnetic solute is readily determined from m and Ai. The diamagnetic mass susceptibilities 0 of the solvents, in SI units of m kg are -8.8 X 10 (benzene), —9.0 X 10 (toluene), and -9.0 X 10 (t-butyl alcohol-water solvent). For temperature-dependence studies, correct m according to Eq. (18), calculate A A/and plot versus HT. The slope of the best straight... 

The Bone Chamber sediments have mass susceptibilities of 500-1000 x 10 m kg, greater than those for pristine aeolian sediments such as the Chinese loesses, which typically have mass susceptibilities of the order of 10-100 x 10" m kg (e.g., Heller and Liu, 1984 Chen et al., 1999). Palaeosols developed within loess sequences, however. 

An independent determination of the density q of the solid is necessary for the calculation of the mass susceptibility (p. 77). 

Here, m is the mass of the sample, x is the mass susceptibility, H the field strength and dH/dS the field gradient. Selwood et measured the force by the...

Evidently, the susceptibility subduced from such experiments is the mean mass susceptibility. This quantity, for linear magnetics, is close to the isothermal susceptibility. However, deviations from linear behaviour increase with... 

As a result of the experiment, the discrete function x° versus Tt is obtained. The mass susceptibility or magnetisation is converted to the molar susceptibility and subjected to the corrections for the underlying diamagnetism and eventually for the temperature-independent paramagnetism, yielding Xmol.i =f(Td-... 

Diamagnetic anisotropy in single crystals may even be enhanced. For example, the diamagnetic mass susceptibility of graphite, with fields either parallel or perpendicular to the hexagonal c axis, is Xu = —264 and x l = —3.8 (in units of 10-9 m3 kg-1).
