Scientific paper

We have obtained low-resolution near-infrared spectra of five SDSS QSOs at 5.3 < z < 6.3 using the NICMOS instrument of the Hubble Space Telescope. We find evidence of emission in the Fe II complex centered near 2500 A (rest) in all five objects. We estimate Fe II / Mg II 2800 A flux ratios comparable to those measured in QSOs at lower redshifts, which indicate metallicities near or above the solar level. We discuss the possible implications of this result assuming the iron enrichment to have been produced mainly in Type Ia supernovae.
