Intralayer doping effects on the high-energy magnetic correlations in NaFeAs

Abstract: We have used Resonant Inelastic X-ray Scattering (RIXS) and dynamical susceptibility calculations to study the magnetic excitations in NaFe 1−x Co x As (x = 0, 0.03 and 0.08). Despite a relatively low ordered magnetic moment, collective magnetic modes are observed in parent compounds (x = 0) and persist in optimally (x = 0.03) and overdoped (x = 0.08) samples. Their magnetic bandwidths are unaffected by doping within the range investigated. High energy magnetic excitations in iron pnictides are robust against … Show more

“…such as neutron scattering [10][11][12][13][14] and / or X-Ray Scattering [15,16]. Neutron scattering experiments confirmed the presence of sizable magnetic moments in Fe pnictides (on the order of ≈ 1 µ B ) [2,3,10] with few exceptions, such as NaFeAs that shows lower ordered magnetic moment [2,3].…”

“…Moreover, the growth of suitable crystals for INS is challenging and this complicates the measurements of high energy spin excitations (> 90 meV), where INS would provide plenty of information [10][11][12]24]. These drawbacks can be minimized by employing RIXS, which has been previously employed in the detection of high energy spin excitations in NaFeAs and BaFe 2 As 2 Fe pnictides [15,16]. Moreover, thanks to the high refocusing (beam spot of 5x20 µm 2 VxH at the ADRESS beamline of the Swiss Light Source) and flux obtainable at the sample for modern beamlines [25], the amount of sample required for these investigations is on the order of tens of milligrams and crystals of the size 150x200 micrometers can now be successfully studied, even measuring down to a single layer of material [26].…”
