A New Ferromagnetic Superconductor: CsEuFe $_{4}$ As $_{4}$

arXiv:1605.09007 · doi:10.1007/s11434-016-1139-2

Abstract

Superconductivity (SC) and ferromagnetism (FM) are in general antagonistic, which makes their coexistence very rare. Following our recent discovery of robust coexistence of SC and FM in RbEuFe $_{4}$ As $_{4}$ [Y. Liu et al., arXiv: 1605.04396 (2016)], here we report another example of such a coexistence in its sister compound CsEuFe $_{4}$ As $_{4}$ , synthesized for the first time. The new material exhibits bulk SC at 35.2 K and Eu $^{2 +}$ -spin ferromagnetic ordering at 15.5 K, demonstrating that it is a new robust ferromagnetic superconductor.
