摘要

这项研究利用溶胶-凝胶技术成功制备出具有理想包晶体晶体结构的银锶锰矿--Sr0.6Ag0.4MnO3。广泛的分析表明了该化合物的显著特点,显示了其在各个领域的潜在用途。X 射线衍射显示,该化合物在室温下呈四方结构,这肯定了它的稳定性。形态和化学评估证实了该材料的一致性和均匀性,结晶平均为 27 nm(X 射线衍射)和 90 nm(扫描电子显微镜)。该材料在 375 K 时显示出铁磁-顺磁转变,表明其适合磁性应用,同时在磁场下电阻略有下降,暗示其具有潜在的磁阻特性,可用于电子设备。在介电性能方面,特别是在低频下,该材料显示出高介电常数和低正切损耗,表明其具有用于电子元件的潜力。总之,这些发现使 Sr0.6Ag0.4MnO3 成为一种多功能材料,在磁学、电子学和电气元件方面具有广阔的应用前景。

Enhancing future technologies: Sol-Gel synthesis of Sr0.6Ag0.4MnO3 manganite perovskite
The research successfully produced Sr0.6Ag0.4MnO3, a silver strontium manganite with the desired perovskite crystal structure, using the sol-gel technique. Extensive analysis revealed its notable characteristics, indicating potential uses across various fields. X-ray diffraction showed the compound's tetragonal structure at room temperature, affirming its stability. Morphological and chemical assessments confirmed the material's consistency and evenness, with crystallites averaging 27 nm (from XRD) and 90 nm (from SEM). The material displayed a ferro-paramagnetic transition at 375 K, suggesting suitability for magnetic applications, alongside a slight drop in electrical resistance under a magnetic field, hinting at potential magnetoresistive properties for electronic devices. In terms of dielectric properties, particularly at low frequencies, the material demonstrated a high dielectric constant and low tangent loss, indicating its potential for electrical components. Overall, these findings position Sr0.6Ag0.4MnO3 as a versatile material with promising applications in magnetism, electronics, and electrical components.
