Abstract
Quasi-static hysteresis loops of assemblies of magnetosome chains of various geometric configurations have been calculated using numerical simulation. A detailed comparison is carried out of the quasi-static hysteresis loops of assemblies of single and double magnetosome chains, as well as assemblies of flux-close rings. It was shown that the hysteresis loops of the studied assemblies differ significantly from each other and from the hysteresis loop of a random assembly of non-interacting spherical magnetite nanoparticles. Therefore, the presence of biogenic magnetite in natural samples of weakly magnetized ancient rocks and ocean sediments can, in principle, be detected from standard measurement of the quasi-static hysteresis loops of the sample under study.
期刊介绍：
The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
