摘要：

We present an extended B-T phase diagram for CeCu2Si2. Elastic constants, ultrasonic attenuation and thermal expansion measurements map besides superconductivity three phases, whose origin is unknown yet. The superconducting phase is embedded in these new phases, which severely constrain the symmetry of the superconducting order parameter. The superconductivity is strongly influenced by Cu deficiencies in contrast to the other phases.
