 Abstract: The differential microcontact resistance between monocrystalline CeCu2Ge2 and simple metals as well as the thermal expansion of CeCu2Ge2 has been investigated. We observed spectra with smooth maxima around +/-3mV, indicating the destruction of AF magnetic order in CeCu2Ge2 and spectra with additional structures that vanish around 0.6K, 1.1K, or 2.6K. The shape of these anomalies and the respective temperatures point to CeCu2Ge2 becoming locally superconducting below these temperatures because of the high pressure exerted by the counter electrodes.
