Magnetic properties of (Fe1-xCox)3BO5 nanorods
摘要
Abstract
Cobalt-doped ferroferriborate ((Fe1−xCox)3BO5) nanorods (NRs) have been synthesized by using a high-temperature organic-solution-phase method, and characterized by high resolution transmission electron microscope (HRTEM) and SQUID. The aspect ratios of the NRs are tuned by reductive decomposition of Fe(acac)3 and Co(acac)2 with a predetermined ratio. HRTEM showS that the sample is polycrystalline NRs and the top view of a NR tip reveals a multiply-twined structure. Magnetization curves indicate that (Fe1−xCox)3BO5 NRs are ferromagnetic above room temperature and the antiferromagnetic component is included, the magnetic properties are dramatically modified by Co substitutional doping. The NRs are expected to be used to study the mechanical properties of biological macromolecules.关键词
