Description

Micromagnetic simulations are performed to study the magnetic and electromagnetic properties of a ferromagnetic tube. Hysteresis loops and possible equilibrium states are observed with external field applied perpendicular and parallel to the tube axis. We found an equilibrium state, which is composed of two oppositely directed vortices, with a domain wall between them. The anisotropic magnetoresistance (AMR) was estimated at every point of the hysteresis loops, in order to investigate its potentiality as an electric device in nano/micro device. As a result, we found that our system can be used as a magnetic sensor that behaves differently according to the magnetic field direction
