Fluence-dependent femtosecond quasiparticle and Eu2+ spin relaxation dynamics in EuFe2(As,P)2
2016
Physical review B
We investigated temperature and fluence dependent dynamics of the time resolved optical reflectivity in undoped spin-density-wave (SDW) and doped superconducting (SC) EuFe_2(As,P)_2 with emphasis on the ordered Eu^2+-spin temperature region. The data indicate that the SDW order coexists at low temperature with the SC and Eu^2+-ferromagnetic order. Increasing the excitation fluence leads to a thermal suppression of the Eu^2+-spin order due to the crystal-lattice heating while the SDW order is suppressed nonthermally at a higher fluence.
