摘要
The equilibrium magnetization states existing in soft magnetic nanotubes and their behavior in external magnetic field are investigated by means of micromagnetic simulation. In the ground state the middle part of a sufficiently long tube is uniformly magnetized along the tube axis, however there are curling states of various circular polarities near the tube ends. The characteristic length of ending curling states, as well as switching field H-s in the external magnetic field parallel to the tube axis, have been calculated as a function of outer tube radius and tube thickness.
