Enhanced spin capturing

Scheme 4.11). The macroradicals are generated either through conventional polymerization initiated by TRI or from dormant chains pre-made by ATRP. The process is called ESCP (enhanced spin capturing polymerization) in the first case and NMRC (nitrone-mediated radical coupling) in the second. The formation of 21 is irreversible at the reaction temperature (<80°C), however,... 

It remains, however, the question whether Tb(0001) exhibits an enhanced Ten as claimed by Rau et al. [124] on the basis of electron capture spectroscopy (ECS). The results of this study show that the electron spin polarization remains non-zero... 

The lanthanide surfaces have an enhanced Curie temperature a surface Curie temperature higher for the surface than for the bulk. This phenomenon was first observed for gadolinium, as indicated in fig. 1. Using spin-polarized electron capture techniques, the surface Curie temperature, T c(surface), was found to be about 17 K higher than the bulk Curie temperature where T c(bulk) = 293 K. Values for the surface Curie temperature...
