| Abstract: | The specific heat of the quasi-onedimensional magnetic compound CuGeO3 shows a sharp anomaly at the spin-Peierls transition temperatureT
sp
. The experimental decrease of the magnetic specific heat belowT
sp
indicates the presence of a spin gap as observed previously with inelastic neutron scattering. A magnetic field of 6T suppressesT
sp
only slightly but reduces the spin gap by a factor of two. |
