摘要：

We have measured the longitudinal elastic constants C-11, C-22, and C-33 of CuGeO3 in magnetic fields up to 20 T. The phase boundaries between the uniform (U), modulated (M), and dimerized (D) phases are associated with large anisotropic variations of the elastic constants. The temperature dependence of the three elastic constants exhibits a minimum at the U-D and U-M phase boundaries. The field dependences of C-11, C-22, and C-33 are reported and the magnetic diagram is determined up to 20 T.
