 Because being in essence bi-stable, magnetic elements may be
integrated in non-volatile memories such as M-RAM's. Conversion from a
"0" to "1" state and vice-versa may be achieved via thermally assisted
switching, precessional switching, spin transfer or even more exotic
modes. For each of these three first modes, selected experiments will be
presented and their interpretation discussed within the framework of
micromagnetics.
