Crystal-field effects in the first-order valence transition in YbInCu4 induced by an external magnetic field
As it was shown earlier [Dzero, Gor'kov, and Zvezdin, J. Phys.:Condens.
Matter 12, L711 (2000)] the properties of the first-order valence phase
transition in YbInCu4 in the wide range of magnetic fields and temperatures are
perfectly described in terms of a simple entropy transition for free Yb ions.
Within this approach, the crystal field effects have been taken into account
and we show that the phase diagram in the plane acquires some anisotropy
with respect to the direction of an external magnetic field.Comment: 4 pages, 3 eps figures; minor changes; to be piblished in J. of
