  Averaged observations of physical phenomena have been utilized for
comprehending specific occurrences in nature; however, these may overlook the
crucial characteristics of individual events, thereby leading to diverse
conclusions. For example, individual wave occurrences such as superposition and
interference yield markedly divergent outcomes when viewed in detail.
Similarly, this study enhances the comprehensive framework of spin-orbit torque
(SOT) within the hysteresis loop shift measurement by employing the average of
effective magnetic fields arising from two distinct magnetic reversals. This
approach facilitates the presentation of a physically descriptive SOT model,
previously characterized only by single chirality qualitatively. By integrating
this model with established measurement methodologies and theoretical
paradigms, we advance a theoretical framework based on the magnetic domain-wall
chirality of individual polarizations and aim to elucidate the phenomena of SOT
with clarity. The anticipated outcomes include the rectification of
inaccuracies in widely employed measurement methodologies and the enhancement
of our comprehension of the fundamental physics, which are expected to propel
advancements in next-generation spintronics materials and devices.
