Physical Review BAbstract
We report the evolution of structural and magnetic properties in La2O3(Fe1-xMnx)(2)Se-2. 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
