摘要：
We have performed a dHvA effect study of CeB6 under high pressure up to 6 kbar. The dHvA oscillation alpha from a main Fermi surface has been observed under pressure, The pressure coefficient d In F/dP of the frequency change is + 1.3 x 10(-3)/kbar and is about three times as large as that expected from the volume compression. On the other hand, the effective mass of ct is found to decrease by about 10% upon application of about 1 kbar and then stays approximately constant up to 6 kbar. (C) 1998 Elsevier Science B.V.
