论文摘要
纳米结构组件之间的交换相互作用是增强材料磁性特性的有效方法。该效果用于交换耦合的磁复合材料，这些磁体由组成阶段的协同影响控制。纹理是需要解决此类复合材料的问题之一。在这项工作中，我们对基于纳米棒阵列的CO/CO3O4纳米复合材料中的交换偏置性质进行了实验和微磁性研究。具体而言，我们研究了所得属性如何根据纳米棒纹理变化。我们的实验证明了以前的理论计算基于交换偏置纳米棒阵列的复合材料，这些复合材料表明，这种材料的磁性取决于内部纹理。调整质地可以导致交换偏置场的增加或增强材料固定性。
The exchange interaction between nanostructured components is an effective way to enhance the magnetic properties of materials. This effect is used in exchange-coupled magnetic composites, which properties are governed by synergetic impact of constituent phases. Texturing is one of the problems that needs to be solved in order for such composites to be used in industry. In this work, we performed experimental and micromagnetic investigation of the exchange-bias properties in Co/Co3O4 nanocomposites based on nanorods array. Specifically, we investigated how the resulting properties will change depending on the nanorods texture. Our experiments proved previous theoretical calculations of exchange-bias nanorods array-based composites that showed that magnetic properties of such materials are dependent on the internal texture. Tailoring the texture can lead to either increase of exchange-bias field, or to enhancement of material coercivity.
