Competition between Magnetic Order and Superconductivity in CeCu2.2Si2
Abstract
We describe muon spin relaxation measurements of the magnetic heavy fermion compound CeCu2.2Si2. Static magnetic order appears below about 1 K, most likely of spin glass nature. We find that the superconducting transition onsetting at 0.6 K partially destroys the magnetic state and that the magnetic volume fraction decreases within the superconducting state. This observation supports the idea that in CeCu2.2Si2, magnetic order and …
