The Temperature Dependence of Magnetic Susceptibility

Fig. 10. Temperature dependence of the magnetic susceptibility of various carbon-based materials. The data on HOPG (H//c) are taken at 200 Oe. The data reported for nanolubes, graphite (H in-plane), and diamond, were taken at 4 kOe, those on diamond at 8 kOe. The ordinate axis is negative (after Heremans et al.[26 ).

The limited magnetic measurements of very mixed -metal clusters are summarized in Table XIII. The magnetic behavior of some anti-ferromagnetic very mixed -metal carbonyl clusters (Fig. 82) has been studied by Pasynskii and eo-workers. Temperature dependences of the magnetic susceptibilities of Cr2Co(/t3-S)3(/i-SBu )(CO)2() -C3H4R)2l (R = H. Me) have been determined us-... 

In Figure 4.5 is reported the temperature dependence of the magnetic susceptibility of four of them, namely R = methyl, ethyl, i-propyl and phenyl.

Ginsberg et al.2917 made a detailed analysis of the average magnetic susceptibility of nickel(II) dimers and fitted the temperature dependence of the magnetic susceptibility of [Ni2(en)4X2]Y2 (X, Y = Cl, Br X = NCS, Y = I). The model Hamiltonian they used is... 

In a subsequent study of the magnetic properties of the Cu2(Et2Dtc)2Cl2 dimer (65) (Fig. 12), the temperature dependence of the magnetic susceptibility... 

Results from magnetic susceptibility studies have been reported (50—53). Measurements (50) obtained by the Gouy method are shown in Figure 3. These are lower than those of other investigators. However, the temperature dependences of the magnetic susceptibilities, %, for the various plutonium allotropes were similar. a-Plutonium single crystals show a slight anisotropy of % (54). 

The Curie paramagnets [e.g., octahedral Fe(III) complexes] are rather rare, and the temperature dependence of the magnetic susceptibility requires more parameters, depending on the actual spacing of the low-lying energy levels. Let us enumerate the MPs associated with the SH formalism ... 

The temperature dependence of the magnetic susceptibility is described by the Curie-Weiss law. When T > 0p,...
