摘要
本文由外斯的分子场理论推出:铁磁物质的居里点要随压强的变化而变化,地球的内核会因受到巨大的压强使居里点提高,超过内核的温度而保持铁磁性,为地磁成因的铁磁体假说找到了依据.
This article explores that the ferromagnetic Curie point is changing along with the intensity of pressure according to the Weiss molecular field theory. Because of the huge intensity of pressure, the inner core of the earth can make the Curie temperature enhance and surpass the temperature of the inner core to maintain ferromagnetism. These prove the hypothesis of ferromagnet on the origin of the geomagnetic field.
