The results on the temperature dependent EXAFS studies of the local structu
re peculiarities of Y1-xYbxNi2B2C series synthesized at a high pressure of
8 GPa are presented. The interrelation between the local structure of Y1-xY
bxNi2B2C and its superconducting and magnetic properties was observed suppo
rting the model where the contributions from all type of the nearest atoms
to the electron-phonon coupling are important and cannot be neglected. (C)
