We report the existence of the type-III short-range spin correlation f
ar above T-N in a single crystal of the low-carrier heavy-fermion comp
ound, YbAs. The correlation lengths parallel and perpendicular to the
[1, 0, 0] direction at (1, 0, 0.5) are obtained to be 2.8 and 4.5 Angs
trom at 1.5 K (similar to 3 T-N), respectively. (C) 1998 Elsevier Scie
