Abstract

The present investigation explores the quaternary metallic glass (MG) Fe_86–2xZr_8+xB_5+xCu₁ (x = 0,1& 2) ribbons that examined for the magnetocaloric effect (MCE) and glass forming ability (GFA) characteristics of the ribbons. The MGs are spun into a ribbon with typical amorphous characteristics by rapid solidification technique and XRD, DSC and VSM have examined their structure and magnetic properties. The observed increase in the α parameter with the increase in the boron and zirconium concentration suggests an increase in the amorphous character of the material. The magnetization-temperature curve demonstrates that the Curie transition temperature consistently increases with the presence of boron and zirconium, and shows a significant shift in entropy, ranging from 1.68 to 2.01 J.kg^-1K^-1 at a magnetic field of 2.5 T. Additionally, it exhibits a noteworthy Relative Cooling Power of 38.76–53.74 J.kg^-1. The potential of this material as an exceptional low-temperature refrigeration material around room temperature is demonstrated by these outcomes.

定制用于磁热应用的Fe86-2xZr8+xB5+xCu1 （x = 1,1 & 2）金属玻璃带的GFA， -∆SM和RC

本研究探讨了Fe86-2xZr8 +xB5+xCu1 (x = 0,1&；2)考察了带的磁热效应（MCE）和玻璃化形成能力（GFA）特性。采用快速凝固技术将镁合金纺成具有典型非晶态特征的带状结构，并用XRD、DSC和VSM对其结构和磁性能进行了表征。α参数随硼和锆浓度的增加而增加，表明材料的非晶性增强。磁化温度曲线表明，随着硼和锆的存在，居里转变温度持续升高，在2.5 t的磁场下，居里转变熵的变化范围为1.68 ~ 2.01 J.kg-1K-1，相对冷却功率为38.76 ~ 53.74 J.kg-1。这些结果证明了这种材料作为室温周围的特殊低温制冷材料的潜力。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
