Magnetic properties complexes

Other complex Ag11 fluorides prepared were A AgF3 (A1 = K, Rb or Cs) which had a similar structure to KCuF3, blue-violet K2AgF4547 and CsAgM1 (Mni = Tl, In or Sc).548 The latter compounds were shown to have the cubic RbNiCrF6 structure and had complex magnetic properties. 

A satisfactory theory of metallic bonding must account for the characteristic properties of high electrical and thermal conductivity, metallic lustre, ductility and the complex magnetic properties of metals which imply the presence of unpaired electrons. The theory should also rationalise the enthalpies of atomisation A/f tom of metallic elemental substances. A/f tom is a measure of the cohesive energy within the solid, and we saw in Chapter 5 how it plays an important part in the thermochemistry of ions in solids and solutions. The atomisation enthalpies of elemental substances (metallic and nonmetallic) are collected in Table 7.1. There is a fair correlation between A/Z tom an(J physical properties such as hardness and melting/boiling points. 

It is clear that there exists a close relationship between the optical and magnetic properties of ferric haemoproteins. Attempts have been made to separate the contributions to the spectrum from the two spin states by making optical and magnetic measurements over a small temperature range (24). Before we discuss the spectra in detail, we must summarise briefly the complex magnetic properties of ferric haemoproteins.

Chromium oxide has a rather complicated electronic structure. It is antiferromagnetic. The so-called spinwaves are difficult to take into account in periodic calculations. The band gap, approximately 3.4 eV, is a bit larger than the one of Ti02. The very complex magnetic properties make the choice of the functional for DFT calculations very delicate. 

Crystal field and exchange field induced mixing of the excited levels (/ = L ) into the ground state (/ = ) accounts successfully for the more complex magnetic properties of Sm " in some intermetallics (Buschow et al., 1973b Dublon et al., 1975).
