摘要：

CoNi chains with length up to a few hundred micrometers have been synthesized via a cetyltrimethylammonium bromide (CTAB)-assisted hydrothermal approach. The product was characterized by means of XRD, SEM, TEM, and VSM techniques. The effects of CTAB amount and reaction time on the resulting CoNi were investigated by a series of assistant experiments. It was found that the CTAB molecule played an important role for the formation of such novel CoNi microchains. These chains assembled by CoNi particles possessed face-centered cubic (fcc) structure. The magnetic property investigation of the obtained CoNi chains illustrated that they display ferromagnetic behavior with significantly enhanced coercivity of 223.3 Oe. (C) 2015 Elsevier B.V.
