Abstract :
This paper deals with the magnetization switching in small ferromagnetic particles. Particularly important for applications, this problem is tackled with two different controls, namely either a horizontal magnetic field or a current polarized in spin.We give in both cases necessary and sufficient conditions for controllability.
