Pressure-induced suppression of ferromagnetism in CePd2 P2

Academic Article


  • The correlated electron material CePd2P2 crystallizes in the ThCr2Si2 structure and orders ferromagnetically at 29 K. Prior work by Lai et al. [Phys. Rev. B 97, 224406 (2018)2469-995010.1103/PhysRevB.97.224406] found evidence for a ferromagnetic quantum critical point induced by chemical compression via substitution of Ni for Pd. However, disorder effects due to the chemical substitution interfere with a simple analysis of the possible critical behavior. In the present paper, we examine the temperature - pressure - magnetic-field phase diagram of single crystalline CePd2P2 to 25 GPa using a combination of resistivity, magnetic susceptibility, and x-ray diffraction measurements. We find that the ferromagnetism appears to be destroyed near 12 GPa, without any change in the crystal structure.
