Structural, magne tic, and f erroelectric properties of BiFeO۳ and BiFe۰.۹۶Co ۰.۰۴O۳multiferroics

Multiferroic materials, exhibit ing simulta neously the magnetic and ferroelectric ordering, have been widely studi ed in recent years, due to their abundant physics and potent ial applicati ons in the sensors, data torage, and spintronics [۱]. Among the rare multiferroic materials, BiFeO۳is one o f the well knownmultiferroicwith G -type antif erromagneti c behavior belowTN~۶۴۳K and fe rroelectric behavior belowTC~۱۱۰۳K [۲]. Much effortha ve been paid to ̱ Ͷ͵magne tization in BiFeO۳. Fe ion ̱ͳͳͲ͵improv e the substitu tion whit other magnetic ions is veryattractive , and enhanced ferromagnetism was reported[۳]. In this w ork we have studied str uctural, magnetic, and ferroelectric propertiesof BiFeO۳and cobalt d oped BiFe۰.۹۶Co۰.۰۴O۳n ano-powder s and ceramics.
