摘要：
Single-crystalline Li2MnO3 nanoribbons have been synthesized via the precursor template Na0.44MnO2 nanoribbons in LiNO3-LiCl eutectic molten salt. The as-prepared Li2MnO3 nanoribbons are characterized by a range of methods including X-ray diffractometer, scanning electron microscope, transmission electron microscope, energy dispersive X-ray spectroscopy, and selected-area electron diffraction techniques. Magnetization measurements show that the Li2MnO3 nanoribbons present weak ferromagnetism, spin-glass-like behavior, and exchange bias effect at low temperature. The magnetic behaviors of Li2MnO3 nanoribbons can be interpreted based on a core-shell model. (C) 2011 Elsevier B.V. All rights reserved.
