论文摘要

Marcasite类的化合物提供了简便的平台,以探索基本和技术重要性的新现象,例如非常规超导性或高性能电催化剂。我们报告了这封信中新的Marcasite Coes的合成和实验研究。使用中子散射测量值对新材料进行的实验研究表明,$ t $ = 36.2 K的钴离子的弱磁相关性弱磁相关性。钴矩之间的适度的各向同性交换相互作用,从随机相位近似分析中推断出来,磁性不稳定的环境的暗示。通过化学压力诱导非常规超导性是一种理想的特征

Marcasite class of compounds provide facile platform to explore novel phenomena of fundamental and technological importance, such as unconventional superconductivity or high performance electrocatalyst. We report the synthesis and experimental investigation of a new marcasite CoSeAs in this letter. Experimental investigation of the new material using neutron scattering measurements reveal weak magnetic correlation of cobalt ions below $T$ = 36.2 K. The modest isotropic exchange interaction between cobalt moments, inferred from random phase approximation analysis, hints of magnetically unstable environment. It is a desirable characteristic to induce unconventional superconductivity via chemical pressure application
