Abstract

The magnetic characterization of the multiferroic composites has become much important for their applicability in improving devices efficiencies. In this report, we have attempted to study the magnetic properties of the multiferroic composites consisting of Mn/Nd doped CoFe₂O₄ and Yb doped PbZrTiO₃ by exploring a new technique called the First Order Reversal Curve (FORC) and also include morphological analysis of the composites and the parent phases. The morphological characterization with the Scanning Electron Microscope confirmed the average grain size decreased with an increase in the ferrite content. The FORC analysis of Mn/Nd doped Cobalt ferrite (CMnFO) and the composites grant the information about the switching field and the interaction field distribution, determining the various magnetic properties of the composites including the magnetic mixtures and the domain state of magnetisation. The FORC analysis also confirmed the nature of the interactions occurring in the system subjected to the shift of the FORC distribution along the interaction axis. The FORC studies determined the existence of the unique magnetic phase CMnFO in all the composites with no additional magnetic phase. The FORC study also describes the influence of the grain size on the FORC distribution of the samples and also the impact of the varying concentration of the ferrite phase on the intensity of the FORC distribution. Further, the Day plots obtained reveal that all the composites and CNdFO have pseudo-domain while the CMnFO phase has a single domain structure.

探索Mn， Nd掺杂CoFe2O4-Yb掺杂PbZrTiO3基复合材料的一阶反转曲线

多铁复合材料的磁性特性对其在提高器件效率方面的适用性变得非常重要。在本报告中，我们尝试通过探索一阶反转曲线（FORC）的新技术来研究Mn/Nd掺杂CoFe2O4和Yb掺杂PbZrTiO3组成的多铁复合材料的磁性能，并包括复合材料和母相的形态分析。扫描电镜形貌分析表明，随着铁素体含量的增加，平均晶粒尺寸减小。通过对Mn/Nd掺杂钴铁氧体和复合材料的FORC分析，获得了开关场和相互作用场分布的信息，确定了复合材料的各种磁性能，包括磁性混合物和磁化畴态。FORC分析还证实了系统中发生的相互作用的性质，这些相互作用受到FORC分布沿相互作用轴的移动的影响。FORC研究确定了复合材料中存在独特的磁相CMnFO，没有额外的磁相。FORC研究还描述了晶粒尺寸对样品FORC分布的影响，以及不同铁素体相浓度对FORC分布强度的影响。此外，得到的Day图显示复合材料和CNdFO都具有伪畴结构，而CMnFO相具有单一畴结构。

期刊介绍： While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including: -insulating to metallic and fast ion conductivity -piezo-, ferro-, and pyro-electricity -electro- and nonlinear optical properties -feromagnetism. When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice. The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
