B = molybdocene(IV) dithiol (70b). The solitaire porphyrazines exhibited rich redox chemistry, and could be oxidized with ferrocenium hexafluorophosphate to yield the paramagnetic Mo(V) species H2[pz(A3B)], A = di -ferf-butyl phenyl, B = molybdocene(V) dithiol (72a) and H2[pz(A3B)], A = dipropyl, B = molybdocene(V) dithiol (72b), which were studied by EPR (Scheme 13). Additionally, 70a was centrally metalated with Cu(II), to form Cun[pz(A3B)], A = di-ferf-butyl phenyl, B = molybdocene(IV) dithiol (71), which was then oxidized to Cun[pz(A3B)], A = di-terf-butyl phenyl, B = molybdocene(V) dithiol (73) and its magnetic properties investigated. [Pg.515]

Several general reports covered more than one type of diazine. For example, Cu(II) complexes of a diverse set of alkoxy diazine ligands were prepared, and their magnetic properties investigated. X-ray crystal structure determinations of many of these were included <04IC4278>. New sulfinylcinnolines, quinoxalines, quinazolines, and phthalazines were prepared from appropriate halobenzodiazines. These were converted to sulfanyl benzodiazines, which in turn... [Pg.304]

A single crystal with the composition Sc0.075Y0.175Gd0.75 with the hep stmeture has been prepared and its magnetic properties investigated by Ito et al. (1988), however, no data about the lattice parameters were presented in this paper. These data indicate a complete miscibility of the components in the ternary system, similar to what occurs in the binary Sc-Y and Sc-Gd systems (see sect. 2.3). [Pg.460]

Thin-film XRD is important in many technological applications, because of its abilities to accurately determine strains and to uniquely identify the presence and composition of phases. In semiconduaor and optical materials applications, XRD is used to measure the strain state, orientation, and defects in epitaxial thin films, which affect the film s electronic and optical properties. For magnetic thin films, it is used to identify phases and to determine preferred orientations, since these can determine magnetic properties. In metallurgical applications, it is used to determine strains in surfiice layers and thin films, which influence their mechanical properties. For packaging materials, XRD can be used to investigate diffusion and phase formation at interfaces... [Pg.199]

In view of this apparent contradictory outcome from the transport and magnetic properties, we were motivated to investigate the dynamics of the charge excitation spectrum by optical methods. In fact, the optical measurement is a powerful contactless experimental tool which should in principle allow to unfold the disagreement between and p(7 since the optical response of a metal... [Pg.90]

The valences of the rare-earth metals are calculated from their magnetic properties, as reported by Klemm and Bommer.14 It is from the fine work of these investigators that the lattice constants of the rare-earth metals have in the main been taken. The metals lutecium and ytterbium have only a very small paramagnetism, indicating a completed 4/ subshell and hence the valences 3 and 2, respectively (with not over 3% of trivalent ytterbium present in the metal). The observed paramagnetism of cerium at room temperature corresponds to about 20% Ce4+ and 80% Ce3+, that of praseodymium and that of neodymium to about 10% of the quadripositive ion in each case, and that of samarium to about 20% of the bipositive ion in equilibrium with the tripositive ion. [Pg.353]

Figure 5a. Variation in the magnetic properties of metal clusters are investigated by measuring the depletion of a highly collimated cluster beam by an inhomogeneous magnetic field, A1 clusters at zero and high field, showing that only small clusters are appreciably deflected.

On the other hand, the XPS data near the Fermi level provide us the valuable information about the band structures of nanoparticles. XPS spectra near the Fermi level of the PVP-protected Pd nanoparticles, Pd-core/ Ni-shell (Ni/Pd = 15/561, 38/561) bimetallic nanoparticles, and bulk Ni powder were investigated by Teranishi et al. [126]. The XPS spectra of the nanoparticles become close to the spectral profile of bulk Ni, as the amount of the deposited Ni increases. The change of the XPS spectrum near the Fermi level, i.e., the density of states, may be related to the variation of the band or molecular orbit structure. Therefore, the band structures of the Pd/Ni nanoparticles at Ni/Pd >38/561 are close to that of the bulk Ni, which greatly influence the magnetic property of the Pd/Ni nanoparticles. [Pg.63]
