Magnetic Hysteresis in Substituted Lanthanum Ferrite La1–xSrxFeO3–δ

Key Points

This research aims to understand how the magnetic moment changes with magnetic field strength in substituted lanthanum ferrite.
Studied hysteresis loops of polycrystalline lanthanum ferrite samples
Analyzed magnetic moment dependences M(H) over a wide temperature range
Examined domain wall behavior in relation to defects present in the material
Established that magnetic hysteresis arises from domain wall pinning
Identified that defects smaller than domain wall thickness influence hysteresis
Demonstrated a clear correlation between temperature and hysteresis behavior

Abstract

The paper studies in detail the dependences M(H) of the magnetic moment on the magnetic field strength in the form of hysteresis loops in a wide temperature range in polycrystalline samples of substituted lanthanum ferrite La0.67Sr0.33FeO3–δ. It has been established that the microscopic mechanism responsible for the formation of magnetic hysteresis in the samples under consideration is the pinning of domain walls to small defects, the dimensions of which are smaller than the thickness of the domain wall.
