BaTiO 3 (BTO) nano-particles with the diameter of 15 nm were prepared by mechanical milling using planetary ball mill from the commercial BTO. Rotation speeds were selected as 0, 100, 150, 200, 250 Meanwhile, much attention was paid to the addition of ferromagnetic property to the ferroelectric substance. Especially, nano-BaTiO 3 (BTO) with vacancies has been expected to be a multi-ferroic system which has the ferromagnetic and ferroelectric properties simultaneously [13][14][15][16][17].In the present paper, a new method to prepare the nano-BTO (15 nm) system and the production of ferromagnetism in this system are reported.

“…The diluted magnetic semiconductors (DMS) has been studied by the present group for TMdoped non-magnetic oxides, where TM was transition metal element and non-magnetic oxides were ZnO [1][2][3], TiO 2 [1,4], SnO 2 [5] and Cu 2 O [6]. In the recent years, the other candidate of room temperature ferromagnetism by vacancies were studied theoretically and experimentally for pure CaO [7], CeO 2 , Al 2 O 3 , ZnO, In 2 O 3 , SnO 2 , HfO 2 , TiO 2 , ZrO 2 [8][9][10][11] and GaN [12].…”

KNO 3 nano-particles with the diameter of about 28 nm were prepared by mechanical milling using planetary ball mill from the commercial KNO 3 powder. Rotation speeds of ball mill were 0 to 500 rpm, where the milling time was kept at 15 minutes. Magnetization was measured by SQUID magnetometer. The milled sample at 500 rpm showed same order of saturation magnetization as that of BaTiO 3 with vacancies.

LiNbO 3 (LNO) nano-particles with the diameter of about 15 nm were prepared by mechanical milling using planetary ball mill from the commercial LNO powder. Rotation speeds of ball mill were 0 to 400 rpm, where the milling time was kept at 15 minutes. Magnetization was measured by SQUID magnetometer. The 400 rpm milled sample showed a tenth larger saturation magnetization than that of BaTiO 3 with vacancies.
