Specific heat of heavy-fermion CeCu/sub 6/: Effect of pressure and magnetic field

OSTI ID:6230610
The specific heat, C, of a single crystal of CeCu/sub 6/ has been measured between 0.06 and 20K to pressures, P, of 8.8 kbar, and between 0.3 and 20K in magnetic fields, H, to 7.5T. At zero H and P, a minimum in C/T is observed near 8K. Below that temperature C/T increases, and below 1K is linear in T, C/T = 1.67 - 0.67T J/mole K/sup 2/. No maximum in C/T is found. This increase in C/T is reduced by a factor of three at 8.8 kbar and virtually completely suppressed for H = 7.5T along the (001) axis. With H parallel (100) and (010) axes the effect on C is small.
