摘要

我们报道了同时具有磁性和超导级的欠掺杂BaFe1.89Co0.11As2的光谱。光电导率的温度依赖演化显示了磁序的指纹和超导间隙的s波性质。对超导态的仔细观察表明，这两个阶在基态中既竞争又共存。

Superconducting transition in the Presence of Magnetic order in BaFe1.89Co0.11As2

We report optical spectra of underdoped BaFe1.89Co0.11As2 that hosts both of magnetic and superconducting orders. The temperature dependent evolution of optical conductivity shows finger prints of the magnetic order and the s-wave nature of the superconducting gaps. Careful inspection on the superconducting state reveals that the two orders compete but coexist in the ground state.

期刊介绍： Progress in Superconductivity and Cryogenics is the official publication of The Korea Institute of Applied Superconductivity and Cryogenics and the Korean Superconductivity Society. It was launched in 1999, and accepts original research articles and review papers on research on superconductivity and related fields of physics, electronic devices, materials science, large-scale applications for magnets, power and energy, and cryogenics. The Journal is published quarterly in March, June, September, and December each year. Supplemental issues are published occasionally. The official title of the journal is ''Progress in Superconductivity and Cryogenics'' and the abbreviated title is ''Prog. Supercond. Cryog.'' All submitted manuscripts are peer-reviewed by two reviewers. The text must be written in English. All the articles in this journal are KCI and SCOPUS as of 2015. The URL address of the journal is http://psac.kisac.org where full text is available. This work was supported by the Korean Federation of Science and Technology Societies grant funded by the Korea government.
