本文考虑了朗道能级对磁星超强磁场衰减的影响。应用3 P2各向异性中子超流理论，得到了一个关于超强磁场的二阶微分方程及其演化时标。普通磁星的超强磁场演化时间为106-107年。根据我们的模型，磁星的活动可能源于高电子费米能引起的不稳定性。
In this paper, we consider the effect of Landau levels on the decay of superhigh magnetic fields of magnetars. Applying3P2anisotropic neutron superfluid theory yield a second-order differential equation for a superhigh magnetic fieldBand its evolutionary timescalet. The superhigh magnetic fields may evolve on timescales ∼(106–107) yrs for common magnetars. According to our model, the activity of a magnetar may originate from instability caused by the high electron Fermi energy.
