Abstract :
Linear Magnetic holes (LMHs) are magnetic field decreasing structures with little change in the field direction. Xiao et al. have studied the geometrical shape and occurrence rate of LMHs in the solar wind at 1 AU from the year 2001 to 2004 by using the magnetic field and plasma data provided by Cluster C1 [1]. In this work, we will investigate LMHs near the region of interplanetary current sheet. It is found that about 60% of LMHs accompanied with the small scale current sheets within 10min. This result may help us to study the formation mechanism of the LMHs in the solar wind.
