Ultrafast destruction and recovery of the spin density wave order in iron based pnictides: a multi-pulse optical study
M. Naseska, A. Pogrebna, G. Cao +3
We report on systematic excitation-density dependent all-optical femtosecond time resolved study of the spin-density wave state in iron-based superconductors. The destruction and r…
Fluence dependent femtosecond quasi-particle and Eu^{2+} -spin relaxation dynamics in EuFe_{2}(As,P)_{2}
A. Pogrebna, T. Mertelj, G. Cao +2
We investigated temperature and fluence dependent dynamics of the time resolved optical reflectivity in undoped spin-density-wave (SDW) and doped superconducting (SC) EuFe(As…
Superconducting gap in BaFe(AsP) from temperature dependent transient optical reflectivity
A. Pogrebna, T. Mertelj, Z. R. Ye +2
Temperature and fluence dependence of the 1.55-eV optical transient reflectivity in BaFe(AsP) was measured and analysed in the low and high excitation den…
Multichannel photodiode detector for ultrafast optical spectroscopy
T. Mertelj, N. Vujičić, T. Borzda +3
Construction and characterization of a multichannel photodiode detector based on commercially available components with high signal to noise of and a rapid frame rate,…
Coexistence of ferromagnetism and superconductivity in iron based pnictides: a time resolved magnetooptical study
A. Pogrebna, T. Mertelj, N. Vujičić +3
Ferromagnetism and superconductivity are antagonistic phenomena. Their coexistence implies either a modulated ferromagnetic order parameter on a lengthscale shorter than the superc…
Spectrally-resolved femtosecond reflectivity relaxation dynamics in undoped SDW 122-structure iron based pnictides
A. Pogrebna, N. Vujičić, T. Mertelj +5
We systematically investigate temperature- and spectrally-dependent optical reflectivity dynamics in AAsFe, (A=Ba, Sr and Eu), iron-based superconductors parent spin-de…
