Abstract
The thermodynamic properties of hydrogen in Mo/V(110) superlattices with 1. 30, 1.17, and 0.74-nm thick V layers were investigated by resistometric mea surements. The hydrogen-hydrogen (H-H) interaction is shown to be repulsive in Mo/V (110) superlattices, whereas it is attractive in (001) oriented sa mples in the same concentration range (H/V<0.45 atomic ratio). This effect is shown to be related to the differences in elastic boundary conditions of the hydrogen absorbing (001) and (110) oriented V layers. (C) 1999 Elsevie r Science S.A. All rights reserved.
