The pressure effects on magnetic susceptibility, specific heat and the co-o
perative Jahn-Teller transition temperature, T-JT, in the single crystallin
e sample are presented. At P = 1.2 GPa susceptibility shows remarkable maxi
mum at T = T-max while specific heat shows no anomalous change around T-max
. However, at T much less than T-JT the upturn of nuclear specific heat is
developed with pressure. Our findings imply that a magnetic ordering is ind
uced by pressure. (C) 2001 Published by Elsevier Science B.V.
