In this study, crednerite CuMnO₂ nanostructures were prepared using a hydrothermal method at 100 °C with various amounts of NaOH mineralizator. Obtained nanostructured crednerite CuMnO₂ with monoclinic structure (space group C2/m) exhibits two morphologies: nanobelts with lengths of 1–1.5 nm and thickness of 15–25 nm, and nanoplates with diameters of 50–70 nm. Comparative analyses of the prepared samples reveal a close relationship between morphological and physical properties of nanostructured CuMnO₂. A low NaOH concentration promotes elongated crystal growth along the c-axis, resulting in nanobelt-shaped morphology. A strong base solution, on the other hand, promotes the formation of nanoplates. The different morphologies of nanostructured CuMnO₂ have different spectroscopic and magnetic properties. The Raman active A_1g mode at 637 cm⁻¹ and a modified Curie-Weiss behavior characterize the nanobelt-shaped sample. This phase has two magnetic phase transitions: ferromagnetic at 9.2 K and antiferromagnetic at 42 K. The nanoplate-shaped sample, on the other hand, exhibits typical behavior as reported in the literature, namely the Raman active A_1g mode at 688 cm⁻¹ and low-dimensional magnetism with antiferromagnetic ordering below 62 K. The variation in magnetic properties is presumably due to partial oxidation of Cu¹⁺/Cu²⁺ and Mn³⁺/Mn⁴⁺, as well as a change in Mn³⁺ spin states from low-spin in nanobelt-shaped samples to high-spin in nanoplate-shaped samples.

在这项研究中，使用水热法在 100 °C 下使用不同量的 NaOH 矿化剂制备了白银矿 CuMnO ₂纳米结构。所获得的具有单斜结构（空间群C 2/ m ）的纳米结构的钙镁石CuMnO ₂表现出两种形态：长度为1-1.5 nm，厚度为15-25 nm的纳米带，以及直径为50-70 nm的纳米片。制备样品的比较分析揭示了纳米结构 CuMnO _{2的形态和物理性质之间的密切关系}. 低 NaOH 浓度促进沿 c 轴的细长晶体生长，从而形成纳米带状形态。另一方面，强碱溶液促进纳米板的形成。纳米结构CuMnO ₂的不同形态具有不同的光谱和磁性。637 cm ^-1处的拉曼活性A _1g模式和改进的居里-魏斯行为表征了纳米带状样品。该相具有两个磁性相变：9.2 K 的铁磁性和 42 K 的反铁磁性。另一方面，纳米板状样品表现出文献中报道的典型行为，即688 cm ^{-1处的拉曼活性}A _1g模式和低维磁性，具有低于 62 K 的反铁磁性排序。磁性的变化可能是由于 Cu ¹⁺ /Cu ²⁺和 Mn ³⁺ /Mn ⁴⁺的部分氧化，以及 Mn ³⁺自旋的变化。从纳米带状样品中的低自旋状态到纳米板状样品中的高自旋状态。
