Abstract

The synthesis of both pristine and lanthanum (La)-doped YBiO₃ (YBO) samples was efficiently carried out via the co-precipitation approach.Yttrium nitrate, bismuth nitrate and lanthanum nitrate salts experienced a chemical reaction at pH 8 and 60 °C temperature, forming a nanometer-sized precipitates, which took polycrystalline form after calcination treatment. The X-ray diffraction examination revealed that these particles existed in single phase and possess face centered cubic (FCC) structure. SEM microscopy elucidated a steady growth in grain size as the concentration of lanthanum was raised. Evolution of magnetic properties in YBi_1-xLa_xO₃(0.00 ≤x ≤ 0.05) specimens have been investigated using MPMS SQUID magnetometer. The thermo-magnetization data study suggested the presence of magnetic domains within YBi_1-xLa_xO₃ (0.00 ≤ x ≤ 0.05). Moreover, magnetic hysteresis loop measurements performed at 2 K also showed existence of weak ferromagnetism in YBi_1-xLa_xO₃ (0.00 ≤ x ≤ 0.05).

YBi₁的可调磁性行为和结构性质相关性（0.00 ≤x ≤ 0.05）：纳米磁性应用的途径

通过共沉淀法有效地合成了原始样品和掺杂镧的YBiO3 （YBO）样品。硝酸钇、硝酸铋和硝酸镧盐在pH值为8、温度为60℃的条件下发生化学反应，形成纳米大小的析出物，煅烧处理后形成多晶。x射线衍射分析表明，这些颗粒以单相形式存在，具有面心立方（FCC）结构。扫描电镜分析表明，随着镧浓度的增加，晶粒尺寸稳定增长。用MPMS SQUID磁强计研究了YBi1-xLaxO3（0.00 ≤x ≤ 0.05）试样的磁性能演变。热磁化数据研究表明YBi1-xLaxO3内部存在磁畴（0.00 ≤x ≤ 0.05）。此外，在2 K下进行的磁滞回线测量也表明YBi1-xLaxO3存在弱铁磁性（0.00 ≤x ≤ 0.05）。
