制备了(1-x)La0.67Sr0.33MnO3/xMnOδ[(1-x)LSMO/xMnOδ]多元复合材料。研究了它们的结构和性能随组成的变化。X射线衍射和X射线光电子能谱证实了MnO、Mn 2 O3和MnO 2的共存。结果表明,MnOδ的引入降低了材料的平均晶粒尺寸和金属-绝缘体转变温度。但它可以增加最大电阻率和磁阻。相应的值为2.0 μm,370 K,0.017 Ω cm,−24.7%(10 K,2 T)(x = 0)和0.7 μm,225 K,1.899 Ω cm,−25.6%(10 K,2 T)(x = 0.3)。铁磁居里温度为305 K,几乎与组分无关。这些结果表明,通过引入铁磁第二相形成多元复合材料可以克服传统铁磁材料的缺点。
(1-x)La0.67Sr0.33MnO3/xMnOδ[(1-x)LSMO/xMnOδ] multicomponent composites were prepared. Their structure and properties were investigated as function of composition. X-ray diffraction and x-ray photoelectron spectroscopy confirmed the coexistence of MnO, Mn2O3and MnO2. It was found that MnOδintroduction led to decreased average grain size and metal-insulator transition temperature. But it can increase maximum resistivity and magnetoresistance. The corresponding values were 2.0 μm, 370 K, 0.017 Ω cm, −24.7% (10 K, 2 T) forx= 0 and 0.7 μm, 225 K, 1.899 Ω cm and −25.6% (10 K, 2 T) forx= 0.3. However, the ferromagnetic Curie temperature was almost composition-independent with the value of 305 K. These results indicate that forming multicomponent composite by introducing ferromagnetic second phases can suppress the drawbacks of conventional ferromagnetic materials.
