Abstract
Iron-based superconductors (IBSs) possess nematic phases in which rotational symmetry of the electronic structure is spontaneously broken. This novel phase has attracted much attention as it is believed to be closely linked to the superconductivity. However, observation of the symmetry broken phase by using a macroscopic experimental tool is a hard task because of naturally formed twin domains. Here, we report on a novel detwinning method by using a magnetic field on FeTe single crystal. Detwinning effect was measured by resistivity anisotropy using the Montgomery method. Our results show that FeTe was detwinned at 2T, which is a relatively weak field compared to the previously reported result. Furthermore, detwinning effect is retained even when the field is turned off after field cooling, making it an external stimulation-free detwinning method.
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.
