Abstract We report on the effect of carbon ion-implantation on the critical behavior of Fe93Zr7 amorphous films. Both the as-grown and carbon-implanted Fe93Zr7 samples exhibit a second order ferromagnetic to paramagnetic transition. The critical exponents were investigated through different techniques such as modified-Arrott plot, the critical isotherm analysis and the Windom scaling relation. Analysis of the critical behavior was presented in terms of the magnetocaloric effect around TC. While there is a significant increase of the magnetization and TC upon C-implantation, the critical exponents were only slightly affected by implantation and were in line with those of the 3D-Heisenberg model.

C注入的Fe93Zr7非晶薄膜的临界行为和磁热效应

摘要 我们报告了碳离子注入对 Fe93Zr7 非晶薄膜临界行为的影响。生长的和碳注入的 Fe93Zr7 样品都表现出二阶铁磁到顺磁的转变。临界指数通过不同的技术进行研究，例如修正的阿罗特图、临界等温线分析和温多姆标度关系。根据 TC 周围的磁热效应对临界行为进行了分析。虽然 C 植入后磁化强度和 TC 显着增加，但关键指数仅受植入影响很小，并且与 3D-Heisenberg 模型一致。
