Nội dung chính của bài viết
Tóm tắt
Hệ hạt nano perovskite lanthanum pha tạp neodymium (La1–xNdxFeO3 với x = 0; 0,1; 0,15 và 0,2 theo công thức lí thuyết) được hình thành từ kĩ thuật đồng kết tủa với sự thêm vào dung dịch sodium hydroxide 5%. Các đặc tính hóa lí của hệ hạt nano La1–xNdxFeO3 tổng hợp được đánh giá bằng các kĩ thuật nhiễu xạ tia X bột (PXRD), kính hiển vi điện tử (SEM, TEM), phổ tán sắc năng lượng tia X (EDX) và hệ đo từ kế mẫu rung (VSM) ở nhiệt độ phòng. Đơn pha tinh thể perovskite La1–xNdxFeO3 hình thành sau khi nung các mẫu bột khô ở 800 °C trong 60 phút. Kích thước trung bình của tinh thể LaFeO3 và thể tích ô đơn vị giảm theo hàm lượng ion Nd3+ pha tạp (DScher = 30,71–27,07 nm; V = 242,62–241,41 Å3). Hệ hạt nano perovskite La1–xNdxFeO3 hình thành được có dạng giả cầu với kích thước ~ 30–50nm. Mẫu bột nano LaFeO3 và La0.8Nd0.2FeO3 mang tính chất của vật liệu thuận từ mềm với các giá trị Hc và Mr xấp xỉ bằng 0, còn độ từ hóa Ms lại rất lớn (~ 0,13–0,19 emu·g–1).
