Muon-Spin Rotation and Magnetization Studies of Chemical and Hydrostatic Pressure Effects in EuFe2(As1−xPx)2

The magnetic phase diagram of EuFe 2 (As 1− x P x ) 2 was investigated by means of magnetization and muon-spin rotation ( μ SR) studies as a function of chemical (isovalent substitution of As by P) and hydrostatic pressure. The magnetic phase diagrams of the magnetic ordering of the Eu and Fe spins...

Description
Summary:The magnetic phase diagram of EuFe 2 (As 1− x P x ) 2 was investigated by means of magnetization and muon-spin rotation ( μ SR) studies as a function of chemical (isovalent substitution of As by P) and hydrostatic pressure. The magnetic phase diagrams of the magnetic ordering of the Eu and Fe spins with respect to P content and hydrostatic pressure are determined and discussed. The present investigations reveal that the magnetic coupling between the Eu and the Fe sublattices strongly depends on chemical and hydrostatic pressure. It is found that chemical and hydrostatic pressures have a similar effect on the Eu and Fe magnetic order.
