Query: Pressure Tuning of the Interplay of Magnetism and Superconductivity in
  CeCu2Si2   We carried out specific-heat and ac-susceptibility experiments under
hydrostatic pressure to investigate the interplay of spin-density-wave
antiferromagnetism (A) and superconductivity (S) in single-crystalline AS-type
CeCu2Si2. We find evidence for a line of magnetic-field- and pressure-tuned
quantum critical points in the normal state in the zero-temperature magnetic
field-pressure plane. Our analysis suggests an extension of this line into the
superconducting state and corroborates the close connection of the underlying
mechanisms leading to the formation of the antiferromagnetic and the
superconducting states in AS-type CeCu2Si2.
