G. Bruls et B. Luthi, COMMENT ON PHONON EFFECTS AT THE METAMAGNETIC TRANSITION IN CERU2SI2 - REPLY, Physical review. B, Condensed matter, 48(17), 1993, pp. 13154-13154
The matter under discussion is the effect of the softening of the elas
tic constants on the metamagnetic transition in CeRu2Si2. In the prece
ding Comment it is argued that some assumptions used in our original p
aper are theoretically unjustified. However, keeping in mind the exper
imental evidence for our assumptions, our feeling is that what is need
ed is a more sophisticated theory.
