摘要

我们揭示了标称成分为 x = 0.05 和 0.1 的立方 Ni2Mn1-xCoxIn 的磁性、电传输特性和普遍磁阻缩放性质。正韦斯温度、相对低磁场中的磁饱和度、非滞后性和非矫顽性特征证实了合金的软铁磁行为。通过反磁感应强度中的格里菲斯相位特征，可以发现在 x = 0.1 的顺磁态中形成了随机铁磁簇。Rhodes-Wohlfarth 分析证实了巡回磁性。这些合金在低温下表现出金属特性和费米液体行为。相对较小的负磁阻表明，巡回自旋波动和传导电子的非相干散射受到抑制。从与磁场强度无关的良好比例归一化磁阻推断出了二阶磁相变。我们的研究激发了人们揭示取代（锰镍和铟的非磁性/磁性）软铁磁镍锰铟基态物理和磁性能的兴趣。

In with nominal compositions of x = 0.05 and 0.1. Positive Weiss temperature, magnetic saturation in relatively low fields, non-hysteretic and non-coercive signatures confirm soft-ferromagnetic behavior of the alloys. Formation of random ferromagnetic clusters in the paramagnetic state for x = 0.1 is noticed through Griffith’s phase signatures in inverse susceptibility. Rhodes–Wohlfarth analysis confirms the itinerant magnetic nature. These alloys exhibit metallic character with Fermi liquid behavior at low temperatures. Relatively smaller negative magneto-resistance indicates the suppression of itinerant spin fluctuations and incoherent scattering of conduction electrons. Second order magnetic phase transition is inferred from a well-scaled normalized magneto-resistance independent of magnetic field strength. Our study stimulates interest to unravel the ground state physical and magnetic properties of substituted (non-magnetic/magnetic for Mn Ni and In) soft-ferromagnetic Ni

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
