Magnetic phase separation in polycrystalline Pr0.5−xBixSr0.5MnO3 (x ≤ 0.15)

Abstract
Abstract In this paper, magnetic phase coexistence and magnetotransport properties of Pr0.5–xBixSr0.5MnO3 (x ≤ 0.15) samples have been studied. Our specimens demonstrate complicated magnetic properties through the presence of several transitions as a function of temperature. With increase in bismuth content, a spin–glass–like–state appears at low temperatures and long–range charge ordering can be observed for x = 0.15. Magnetization and resistivity seems to be sensitive to magnetic field cycling, testifying the presence of training effect. Both, magnetic phase separation phenomenon and 6s2 lone pair electrons of Bi3+ ions, play a key role in the governance of the physical response of studied specimens.
