Theoretical study of magnetic properties of SrMn_1‐xFe_xO₃ perovskites

Abstract

Purpose

This paper aims to combine the results of magnetic measurements with high temperature series expansions to determine the magnetic phase diagram of SrMn_1−xFe_xO₃ 0≤x≤1 perovskites materials.

Design/methodology/approach

The authors have found antiferromagnetic ordering for lightly and heavily Fe‐substituted material, while intermediate substitution leads to spin‐glass behavior. Near the SrMn_0.5Fe_0.5O₃ composition these two types of ordering are found to coexist and affect one another.

Findings

The spin glass behavior may be caused by competing ferromagnetic and antiferromagnetic interactions among Mn⁴⁺ and observed Fe³⁺ and Fe⁵⁺ ions.

Originality/value

The magnetic perovskites materials are several application in industrial applications (spintronics, magnetic random‐access memory (MRAM), …).
