Dependence of magnetic ordering temperature of doped and undoped EuFe 2As2 on hydrostatic pressure to 0.8 GPa

Academic Article

Abstract

  • The ac susceptibility of single crystalline tetragonal EuFe 2As2, 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. © 2011 Elsevier B.V. All rights reserved.
