生物磁铁矿的磁各向异性与磁接收器
Magnetic anisotropy of biomagnetite and magnetoreceptor
摘要
Abstract
Magnetite distributes abroad and is a most important ferrous material in nature, and also distributes a-broad in living bodies.Biomagnetites have pure crystal structure and most are superparamagnetic particles and single domain particles with obvious magnetic anisotropy.Magnetoreceptor exists in these living bodies with bio-magnetite being the biophysics base.In this paper, from the point of view of physical characteristics of super-paramagnetic particles and single domain particles, mainly from the point of view of magnetic anisotropy of them, the working mechanism of biomagnetite and magnetoreceptor are discussed.That is in some condition, by the effect of magnetic field sizable as geomagnetic, superparamagnetic particles and single domain particles can be induced to produce magnetic field enough to let crystals adjacent repel or attract, the effect of these particles can change the shape of the outer organic matter of these particles, so nerves can detect the outspread or shrinkage of these particles and then the living bodies can detect the direction and intension of outer magnetic field.关键词
