Extended Data Fig. 4: Electronic structure at different photon energies.
From: Observation of plaid-like spin splitting in a noncoplanar antiferromagnet
a–c, CECs at binding energy EB = 0.35 eV measured with 54-eV, 92-eV and 100-eV photons. The CEC at 92 eV show a rectangular feature close to the zone centre (in good agreement with the DFT result shown in the inset), whereas the other two maps show a cross shape in the first zone. This kz dispersive behaviour indicates the bulk nature of the bands. d–f, ARPES E–k dispersion taken with 76-eV, 92-eV and 102-eV photons. Purple curves are the bulk bands calculated by DFT. The qualitative match between the DFT bands and the ARPES data probably indicates that the ARPES intensity comes mostly from bulk states of the system.
