Abstract :
The anomalous Hall effect has been recognized as a useful tool for measuring the magnetic hysteresis M(H) loops of perpendicular magnetic recording media (PMRM), and has shown particular utility for characterizing double-layered PMRM since the loops for both the recording layer (RL) and soft under layer (SUL) may be measured simultaneously, a task not easily accomplished using conventional magnetometers because of the difficulty associated with extracting the properties of the RL and SUL individually.
