| Popis: | We synthesized Mn3Zn0.9Cu0.1N by solid state reaction, and magnetic as well as electrical transport properties were investigated. It is found that Mn3Zn0.9Cu0.1N exhibits a first-order antiferromagnetism (AFM) to paramagnetic (PM) transition with the Néel temperatureTN~163 K, and substitution of Cu for Zn would favor ferromagnetism (FM) state and weaken AFM ground state, leading to a convex curvature character ofM(T)curve. With high external fields 10 kOe–50 kOe, magnetic transition remains a robust AFM-PM feature while FM phase is completely suppressed. Thermal hysteresis ofM(T)under 500 Oe is also suppressed when the magnetic field exceeds 10 kOe. Mn3Zn0.9Cu0.1N exhibits a good metallic behavior except for a slope change aroundTN, which is closely related to AFM-PM magnetic transition. Compared with the first differential of resistivity with respect to temperature for(dρ/dT)Mn3ZnNin transition temperature range, the absolute value of(dρ/dT)Mn3Zn0.9Cu0.1Nis much lower which is close to zero. |
