英文摘要	Single-crystalline and monodisperse manganese oxide (MnO and Mn(3)O(4)) nanoplates have been synthesized via a modified nonhydrolytic approach, using manganous acetate as the precursor in oleylamine, and subsequent controlled oxidization with trimethylamine N-oxide. The formation of MnO nanoplates seems a highly kinetics-driven process, which proceeds under a quite high monomer concentration. Along with manipulating the post-treatment procedure and polarity of dispersants, the as-obtained nanoplates are aligned to form self-assembly narroarrays either in "side-to-side" formation or "face-to-face" formation. Meanwhile, the MnO and Mn(3)O(4) nanoplates display ferromagnetism at low temperatures. The as-obtained Mn(3)O(4) nanoplates exhibit a coercive field of 8.9 kOe at 5 K, significantly higher than those of bulk Mn(3)O(4) and thin films.; Chemistry, Physical; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; SCI(E); EI; 13; ARTICLE; 16; 6521-6528; 113
