Magnetic properties of BiFeO3 micro-cubes synthesized by microwave agitation

TL;DR

This study investigates the magnetic properties of BiFeO3 micro-cubes synthesized via microwave agitation, revealing domain growth behavior and aging effects without spin-glass characteristics.

Contribution

It provides new insights into the magnetic behavior of microwave-synthesized BiFeO3 micro-cubes, highlighting domain dynamics and aging phenomena.

Findings

Difference between FC and ZFC magnetizations at ferromagnetic domain wall freezing temperature

Decay of magnetic moment follows a power-law relation

Absence of memory effect suggests domain growth mechanism

Abstract

In this report we present results of magnetization measurements and investigation of aging and memory effect in bismuth ferrite multiferroic micro-cubes obtained by means of simple microwave synthesis procedure. It is found that difference between FC and ZFC magnetizations appears at the temperature of freezing of ferromagnetic domain walls. The decay of the magnetic moment vs. time described by power-law relation and the absence of memory effect indicate domain growth mechanism rather than the spin-glass phase.
