| Анотація | We studied the electronic and magnetic properties for the Mn-doped chalcopyrite AlGaP2 semiconductor by using the first-principles calculations. The Mn-doped AlGaP2 yields strong half-metallic ground states. The ferromagnetic state is the most energetically favorable one. The states of host Al, Ga, or P atoms at the Fermi level are mainly a P-3p character, which mediates a strong interaction between the Mn-3d and P-3p states. The ferromagnetic ordering of dopant Mn with high magnetic moment is originated from the P(3p)-Mn(3d)-P(3p) hybridization, which is attributed by the partially filled P-3p bands. The high magnetic moment of Mn by P vacancy is produced by 4.2 μB/Mn. |
