The compounds have been shown to possess the noncentrosymmetric rhombohedral structure specific to the parent Bi0.95Ca0.05FeO2.975. B-site substitution eliminating the oxygen vacancies suppresses a weak ferromagnetic contribution characteristic of the low-doped Bi1\u2212xCaxFeO3\u2212x\/2 ferrites. Over-compensatory Ti4+ doping (resulting in the appearance of cation vacancies in the host lattice) restores the weak ferromagnetic phase. The lattice defects dramatically affect both microstructure and ferroelectric domain structure of the Bi0.95Ca0.05Fe1\u2212yByO3 perovskites and tend to decrease an average size of crystal grains and ferroelectric domains. These observations pave the way for understanding the conditions favoring the coexistence of spontaneous magnetization and polarization in BiFeO3-based multiferroics.<\/jats:p>","DOI":"10.1063\/1.4903315","type":"journal-article","created":{"date-parts":[[2014,12,3]],"date-time":"2014-12-03T18:00:29Z","timestamp":1417629629000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":19,"title":["Spontaneous magnetization in the polar phase of Bi1\u2212xCaxFeO3\u22122\/x perovskites: The role of anion vacancies"],"prefix":"10.1063","volume":"116","author":[{"given":"V.
