We measure the relationship between stellar mass and stellar metallicity, the stellar mass–metallicity relation (MZR), for 1336 star-forming galaxies at 1.6 ≤ z ≤ 3.0 (〈z〉 = 2.2) using rest-frame farultraviolet spectra from the zCOSMOS-deep survey. High signal-to-noise composite spectra containing stellar absorption features are fit with population synthesis model spectra of a range of metallicity. We find stellar metallicities, which mostly reflect iron abundances, scaling as (ZFe,∗/ZFe… Expand
