Room-temperature multiferroicity material, method for preparing same, and electronic device comprising same

A method for preparing a room-temperature multiferroicity material, the method comprising steps of:

• forming a first mixture by mixing a lead oxide, an iron oxide, a niobium oxide, and a ferromagnetic element;
• forming a second mixture by mixing a lead oxide, a bismuth oxide or a barium oxide, and a titanium oxide, a zinc oxide, or both thereof;
• mixing the first mixture and the second mixture to obtain a mixed mixture;
• calcining the mixed mixture to obtain a calcined mixture;
• and
• sintering the calcined mixture,
• wherein the room-temperature multiferroicity material includes a compound of Chemical Formula 2 below in a compound matrix of Chemical Formula 1 below:
• (Pb1-xTMx)Fe1/2Nb1/2O3 [Chemical Formula 1]
• (In Chemical Formula 1, TM includes at least one selected from the group consisting of Fe, Ni, and Co, and x is a number greater than 0 and less than 1)
• ABO3 [Chemical Formula 2]
• (In Chemical Formula 2, A includes Pb, Bi, or Ba, and B includes Ti, Zr, or both).
