The field-induced change in the X-ray absorption spectrum near the Ce-L3 edge is found to be smaller than the resolution limit of the measurement, suggesting that no field-induced valence change larger than 0.005 takes place at 2 K up to 42 T.}, title = {Valence State in CeIrIn5 at High Magnetic Fields of up to 42 T}, volume = {85}, year = {2016} }
