摘要：

A magnetic transition from ferromagnetism to ferrimagnetism occurs in hexagonal alloy Mn2.1FeSn0.9. The mechanism for this transition has been explored according to the electronic structure by first-principles calculations. An energy difference of only 0.12 eV/f.u. was found between the two magnetic phases, thus the magnetic transition can be suppressed by the magnetic field. The large exchange anisotropy due to the coexistence of ferrimagnetic (FIM) and ferromagnetic (FM) phase causes a large exchange bias field up to 3.85 kOe at 5 K. A semiconductor-like to metallic behavior transition and an increase of hole carrier concentration have been observed during the FM -> FIM transition due to the reconstruction of Fermi level. This illustrates that the physical properties of Mn2.1FeSn0.9 can be easily regulated by the magnetic structure.
