Physical Review B
Understanding the underlying mechanism and phenomenology of colossal magnetoresistance in manganites has largely focused on atomic and nanoscale physics such as double exchange, phase separation, and charge order. Here we consider a more macroscopic view of manganite materials physics, reporting on the ferromagnetic domain behavior in a bilayer manganite sample with a nominal composition of La_2-2xSr_1+2xMn_2O_7 with x=0.38, studied using in-situ Lorentz transmission electron microscopy.
