摘要

零散射Ti:Zr合金(Ti67.6Zr32.4)由于不会从样品环境中产生污染物布拉格反射而被广泛应用于样品容器、压力电池和衬垫的中子散射。本文报道了该材料的超导性，临界温度T c = 1.4 K，下临界场Hc1≈100 Oe，上临界场Hc2≈4500 Oe。这些特性在很大程度上与在所有供应商的材料中发现的少量铁磁性铁的数量无关。本研究结果对Ti:Zr材料在应用场和低温中子散射实验中的应用具有重要意义。

Superconductivity in null-scattering Ti:Zr alloy

Null-scattering Ti:Zr alloy (Ti67.6Zr32.4) is widely used in neutron scattering for sample containers, pressure cells and gaskets since it does not produce contaminant Bragg reflections from the sample environment. Here we report superconductivity in this material with critical temperature T c = 1.4 K, lower critical field Hc1≈ 100 Oe and upper critical field Hc2 ≈ 4500 Oe. These properties are largely independent of the amount of a small quantity of ferromagnetic iron found in materials of all providers. Our findings bear on the use of Ti:Zr in neutron scattering experiments at applied field and low temperatures.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
