The magnetization process is strongly dependent on the magnetostriction constant and the magnetoelastic anisotropy induced by internal stresses (Vázquez et al. 1996 ). Glass coating induces an extra radial internal stress due to the different thermal expansion coefficients of the nucleus and the glass.

· September 25, 2021. Mixture separation methods are physical techniques used to separate the components of a mixture. A mixture can be homogeneous, when its components are not visible to the naked eye, or heterogeneous, when the differences between its components are evident. The importance of these methods is that they allow us to obtain pure ...

· Abstract: We have developed a new water-treatment system consisting of a membrane separator and a magnetic separator that uses long (>200 mm) high-temperature bulk superconductors (SCs) as permanent magnets. For magnetizing the long bulk SCs, we developed a new magnetization method. Namely, a field is applied, the bulk SCs are cooled below their …
· 1 Introduction. Anisotropy of magnetic susceptibility (AMS) is determined from the directional variability of the magnetization (M i) in an applied field (B j).It can be described mathematically as a symmetric second-rank tensor (k ij) and can be represented physically by an ellipsoid with three principal axes.For the anisotropy of the magnetic susceptibility the …
Selective crystallization represents one of the most economical and convenient methods to provide large-scale optically pure chiral compounds. Although significant development has been achieved since Pasteur's separation of sodium ammonium tartrate in 1848, this method is still fundamentally low efficient (low transformation ratio or high labor).
· The approximately 1 per cent variation in magnetization when rotated parallel to the core axis is likely due to slight variations in the sample position and contributions from the sample holder. Due to sample shape there is a variation in the observed magnetization of 16 per cent for a 51 mm pole spacing and 3 per cent for a 97 mm pole spacing.
