Tóm tắt

Magnetite (Fe3O4) là vật liệu tiềm năng trong việc phát triển các thiết bị spintronic nhờ sở hữu nhiệt độ Curie cao (585 ℃) và cấu trúc bán kim loại (half-metallic) với duy nhất một phân cực spin (spin polarization) ở mức Fermi. Tính chất vật liệu khối của Fe3O4 khiến việc chế tạo các màng mỏng có độ hợp thức cao ở nhiệt độ thấp là một thách thức lớn. Trong bài báo này, chúng tôi báo cáo sự phát triển cấu trúc và hình thái của màng mỏng Fe3O4 khi thay đổi tốc độ dòng khí. Phún xạ magnetron tần số vô tuyến (radio frequency - RF) đã được sử dụng để chế tạo màng mỏng Fe3O4 trên đế SiO2 ở nhiệt độ phòng. Kính hiển vi lực nguyên tử (Atomic force microscopy - AFM) cho thấy hạt có hình dạng giống hình cầu, độ nhám hiệu dụng (root mean square - RMS) thay đổi từ 1,5 nm đến 7,5 nm và kích thước hạt tăng từ 30 nm đến 74,3 nm. Cấu trúc của màng Fe3O4 được cải thiện đáng kể bằng cách tăng tốc độ dòng khí. Ngoài ra, sự xuất hiện của điểm chuyển Verwey dưới 120 K khi đo điện trở suất (p) theo nhiệt độ (T) cũng cho thấy sự tồn tại của Fe3O4.
