Description

We have investigated the electronic phase diagram of the 1111 Fe-pnictide CeFeAs1-xPxO by means of muon spin relaxation (μSR). From resistivity and magnetic susceptibility a rich variety of electronic ground states including antiferromagnetism, ferromagnetism and superconductivity is inferred. We find that the examined compounds show a strong polarization of the rare earth moments by the long range ordered iron sublattice for x <= 0.4 and independent order of the Cerium-4f moments and short range ordered iron moments for x > 0.4. The peculiar interplay of the rare earth and iron magnetic order as a function of chemical pressure is examined. We further investigated the ground state properties of the heavy fermion system CeFePO.
