The magnetic phase transition and geophysical crustal anomalies

摘要

Kiss et al. (2005) suggested to consider the phenomenon of second-order magnetic phase transition in the Earth's crust, as a possible source of geomagnetic and magnetotelluric anomalies. In that paper two consequences were mentioned: (1) some geomagnetic anomalies of unknown origin could be perhaps phenomenon might be also responsible for some magnetotelluric crustal conductivity anomalies. Since that time new problems and challenges have emerged. In this paper we refresh the conclusions, and summarize the new results. In spite of some scepticism, there are more and more theoretical and experimental results (in solid state physics), which bring more and more probable that magnetic phase transition sometimes might be a potential source of various geophysical crustal anomalies.
