[(Li0.8Fe0.2)OH]FeS and the ferromagnetic superconductors [(Li0.8Fe0.2)OH]Fe(S1−xSex) (0 < x ≤ 1)†
Abstract
Superconductivity up to 43 K and magnetic ordering coexist in the iron chalcogenides [(Li0.8Fe0.2)OH]Fe(S1−xSex) (0 < x ≤ 1). Substitution of sulphur for selenium gradually suppresses superconductivity while the ferromagnetic signature persists up to non-superconducting [(Li0.8Fe0.2)OH]FeS.
