Magnetic semiconductors have become a widely studied direction in spintronic materials due to their unique energy band structure and two different spin transport channels. In this work, we imported rare-earth atoms into quaternary Heusler compounds and considered on Slater-Pauling rules. Magnetic semiconductors FeCrYSn, FeCrYGe, FeCrLuGe, FeCrLuSn, FeCrLuSi, FeVLuSb, MnCrYSb, and MnCrLuSb were found through first-principle calculations. According to the result, the band gaps of these quaternary Heusler compounds are extremely narrow.
