摘要

实验表明, 自然界中许多动物能感受到磁场信息, 尤其是鸟类能够依靠地磁信息导航归巢或迁徙. 鸟类磁感受机理认为, 鸟类可以通过感受地磁场的强度与倾角建立磁地图从而进行飞行导航. 目前对鸟类用于感受磁场的磁受体的研究仍然处于探索鉴定阶段, 研究铁矿物结构是否具有在生命系统中作为磁受体的物理磁学性质有着十分重要的意义. 本文使用微磁学方法对鸟类基于铁矿物的磁感受机理中的磁赤铁矿片晶状磁受体结构进行三维模拟分析, 对其在地磁场中的畴态及对磁场信息的响应作用进行探究. 结果表明, 自然畴态为涡旋态的磁赤铁矿片晶链具有感受地磁场方向变化的能力.

Abstract

Experiments demonstrate that large varieties of animals have the ability to sense the magnetic field. Especially, some birds can use the geomagnetic field for navigation. According to the avian magnetoreception mechanisms, birds can build magnetic map for orientation and navigation by sensing the intensity and incline of geomagnetic field. However, researches on the magnetoreceptor of birds are still at the stage of discovery and identification, and it is necessary to study the iron-mineral-based structures to know whether they have the physical and magnetic properties to act as magnetoreceptor in living system. In this paper, the maghemite platelet chains in the iron-mineral-based magnetoreceptor have been studied with three-dimensional simulation based on the theories of micromagnetics. The reaction of the maghemite platelet chains with geomagnetic field has been investigated. Result indicates that the maghemite platelet chains with vortex domain can response to the change of the orientation of geomagnetic field.
