From A AS estimations, the ratio of rare earth metal to transition metal was found to be quite different in solid composites synthesized in sonication conditions compared to normal conditions. In all the cases of rare earth-transition metal-Ti02 composite the concentration of both transition metals (Cu and Co) and rare earths (La, Sm and Gd) was found changed due to sonication. The composition of transition metals (Cu and Co) was found to be lower compared to rare earths (La, Sm and Gd) respectively in solid composites synthesized in sonicated conditions than those solid composites synthesized in normal conditions (Table 11.1). In other words we can say that the concentration of rare earths to transition metal is...

General consideration of magnetism in rare-earth-transition metal alloys... 

Amorphous alloys are characterised by a structural disorder where each atom constitutes a structural unit. In this state, the low mass density and the loss of the periodicity enhance the localisation of the 3d electrons in the rare earth-transition metal alloys. In... 

The investigation of the whole family of these multilayer compounds would help to understand the mechanisms for superconductivity and magnetism in the quaternary rare-earth transition-metal borocarbides (Michor et al. 2001 Baggio-Saitovitch et al. 2001). However this report will be confined to magnetism and superconductivity in singlelayer / Ni2B2C compounds i.e. compounds with (/ C/N) Ni2B2 with n > 1 will not be considered further.
