Title: Magnetism in La₂O₃(Fe₁₋xMnx)₂Se₂ tuned by Fe/Mn ratio

Journal Article · · Physical Review. B, Condensed Matter and Materials Physics

We report the evolution of structural and magnetic properties in La₂O₃(Fe₁₋xMnx)₂Se₂. Heat capacity and bulk magnetization indicate an increased ferromagnetic component of the long-range magnetic order and possible increased degree of frustration. Atomic disorder on Fe(Mn) sites suppresses the temperature of the long-range order whereas intermediate alloys show a rich magnetic phase diagram.
