Light-induced enhancement in magnetization is observed at room temperature in the metamagnetic Fe3Ga4 grains formed by the alternative deposition of Fe3Ga2-xAsx and GaAs on GaAs(001) substrates. The illumination power dependence of the enhanced magnetization is compared with the antiferromagnetic-type magnetization–temperature ($M$–$T$) curve (Néel temperature of $T_{\text{N}}=340--390$ K), and, in addition with the enhancement due to light-induced heating, the possibility of photoenhanced magnetization is discussed.
