The wall atate stability of magnetic bubbles in fertimagnetic aagrown garnet film8 suitable for Bloch line "mory applications is inveatigated in order to predict the atability of vertical Bloch line p i t a . In the experiment (1,O) and ( 0 , 2 ) bubble8 are subjected to fast biaa pulues (15 ns width) and to an in-plane field Hip. It ia found that the winding line pair preaent in a ( 0 , 2 ) bubble can be annihilated, resulting in a (1,O) final atate. On thm other hand a (1,O) bubble c8a be switched into a ( 0 , 2 ) bubble w i t h different erperiment8l conditions. These non-conservative switching proceasea are in moat caaea irreversible. However the awitching probability never reaches 100%. An intarpretation o f the annihilation mechanism ia given and the conaequencea for devices are discussed.

Motion equations for the magnetic bubble domain containing a small number of the Bloch lines are derived in the framework of the Lagrange formalism. The analysis of the Döring kinetic term is given in the nonstationary case. The linear responses of a single bubble domain are considered and the stability of the pair of the vertical Bloch lines of opposite signs is examined. The threshold magnitude of the driving magnetic field is found. Static 2D domain wall structures describing the intersection of the two Bloch lines are obtained.
