Temperature dependence of magnetic

Ishikawa etal. proposed an approach for the determination of the ligand-field (LF) parameters of a set of isostructural lanthanide complexes. This method consists of a simultaneous fit of the temperature dependence of magnetic susceptibilities and NMR spectra for the whole isostructural series [18]. In order to avoid over-parametrization a key restriction is imposed each parameter is expressed as a linear function of the number of f electrons, n ...

Temperature dependence of magnetic susceptibility of the PF6 salt was measured from 300 to 4 K at 5 T [35], The spin susceptibility of this salt gradually decreases from 300 to 50 K. Below 50 K, the susceptibility exhibits a rapid decrease accompanied by anisotropic temperature dependence, which is an indication of the long-range antiferromagnetic ordering. A one-dimensional Heisenberg model is... 

The temperature dependence of magnetic susceptibility x measured on single crystals reveals magnetic ID behaviour. Below 50 K x is strongly anisotropic with the trigonal axis corresponding to the easy axis of magnetization and therefore to...

Abstract. Two forms of CoO have been prepared from spec, pure Co metal and CoC03 and the magnetic susceptibility of CoO(I) and CoO(II) examined over a temperature range300-700 deg. K. The magnetic data of CoO(II) have shown an anomalous temperature dependence of that in this temperature range CoO(II) passes into CoO(I). This result is in conformity with Mossbauer spectra. Furthermore, D.T.A and temperature dependence of magnetic susceptibility of CoO(II) arises from a first order phase transition. 

During the measurements of the temperature dependence of magnetization (a(T)), the sample has been placed in a chamber with constant hydrogen pressure. In order to determine the hydrogen concentration x in the sample at any temperature (x(T)), a volumetric type experimental set-up [10, 11] has been used to study the hydrogen absorption-desorption properties at hydrogen pressures up to 4 atm in the temperature range from 300 to 700 K.
