Exchange-striction of rare earth-Al2 Laves phase compounds
Description
The exchange-striction of the cubic Laves phase compounds R-Al2 (R = Gd, Tb, Dy, and Ho) has been determined at 0 K from measurements of thermal expansion. The results are interpreted in terms of rare earth sublattice (R-R) interactions, using the molecular field approximation. It is found that the signs of the strain derivatives of the molecular field constants are positive for Dy-Al2 and Ho-Al2 and negative for Gd-Al2 and Tb-Al2 compounds. (author)
