“…In order to reduce wellknown Bi volatilization [54,55], 2.5% access Bi 2 O 3 was incorporated in all samples. The use of excess amount of Bi 2 O 3 is routinely reported in the literature [56][57][58]. Since melting point of Bi 2 O 3 and Eu 2 O 3 are significantly different, therefore temper ature and time for calcination and sintering for all the compositions were optimized.…”

We have systematically investigated the effects of Eu substitution on chemical pressure, bond lengths, microstrain, bond angles, octahedral tilting, vibrational modes and phase transformation, in BiFeO. Correlation between concentration, phase, local structure and magnetism has been explained. Substitution of Eu ions with contrasting magnetic moment and dissimilar size, affects the local structure by changing bond angles and hence modifies spin structure through weakening of Dzyaloshinsky-Moriya (DM) interaction which lead to destruction of spiral spin configuration. Intriguing as well as anomalous magnetic response such as weak ferromagnetism with high coercivity, stair step like loops with significant drop in coercivity and systematic decrease in the magnetic coercivity at low temperatures has been observed as a function of Eu concentration (x). These results are explained on the basis of weakening of DM interaction, field induced melting of antiferromagnetic clusters and modification in effective magnetic anisotropy including contribution of magnetoelectric coupling, for various values of x. These results were used to generate the magnetic phase diagram.

“…Therefore, the grains were found to have angular shape rather than curved surfaces. This was because the angular surface had surface energy less than curved surfaces [31]. The EDX patterns also conclude the completion of chemical reaction of the precursor to form the desired materials without any loss of ingredients during the sintering process.…”
