   Abstract: The influence of annealing on giant magnetoresistance (GMR)
   effect and magnetization reversal processes has been investigated in
   Py/Cu (Py = Ni83Fe17) sputter-deposited multilayers (MLs) with a
   limited number of magnetic sublayers (N less than or equal to 6) and
   equal sublayer thicknesses both for Py and Cu (t(Cu) = 2 nm, t(Py) = 2
   nm). Based on the magnetization and magnetoresistance measurements it
   has been shown that the magnetic behavior of such MLs is strongly
   influenced by annealing driven disruption of magnetic layers (lateral
   decoupling) and nonmagnetic layers (magnetic bridging between Py
   layers). A comparison of experimental hysteresis curves with model
   dependences indicates that annealing causes a change of the
   magnetization reversal from a local to an absolute energy minimum mode
   leading to quasi-two-state magnetoresistance characteristics.
