| Abstract: | The ac susceptibility of single crystalline tetragonal EuFe2As2, EuFe2As1.4P0.6, and EuFe1.715Co0.285As2 has been measured over the temperature and hydrostatic (He-gas) pressure ranges 10–60 K and 0–0.8 GPa, respectively. For all three samples the magnetic ordering temperature (17–19 K) from the Eu sublattice increases linearly with pressure, presumably due to the enhanced exchange coupling between Eu-layers. No evidence for a superconducting transition was observed in the susceptibility for any sample over the measured temperature/pressure range. |
