It was found that around x ~ 0.06 the crystal symmetry changes from a rhombohedral (space group R3c) to pseudo-tetragonal. In the range 0.07<x<0.14 the phases with different symmetry of the unit cell coexist independent of synthesis conditions. The Bi1-xAxFeO3 (A = Ca, Sr, Pb, Ba; x <0.5) systems have been studied using the Mossbauer spectroscopy and magnetization measurements in a magnetic field up to 14 T. The magnetic structure for Bi1-xAxFeO3 (x<0.5, A = Ca, Sr) is found to be G-type antiferromagnetic with magnetic moment of about 3.8 µB/Fe3+. Product Description popup.authors Єременко В.В.
