a XMCD spectra for selected applied B-fields. Top inset: zoom into the Mn L3 edge, showing two distinct spectral weight from substitutional Mns and interstitial Mni atoms. Bottom inset: background subtracted XAS spectra for ± μ light polarizations, measured at B = 6 T (10 K), and overlaid with multiplet calulations. b Series of MnL3 XMCD spectra taken at ≈6 min intervals for selected B-fields. c Spontaneous switching recorded in two consecutive XMCD datasets (red/blue) in the absence of applied B-field, shown at the MnL3 (main graph) and MnL2 (inset) absorption edges. d MnL3-edge model based on 4 Gaussian functions simulating Mns and Mni spectral contributions. For PM the Mns and Mni features are aligned, with their amplitude dependent on the B-field. The FiM consists of oppositely aligned peaks with different amplitude. M and MSW refer to the reference and switched state respectively.
