The purpose of the research is the construction of an analytic model for the description of a spin-polarized current-driven ferromagnetic domain wall motion with a skyrmion-like building block. The motion velocity of the ferromagnetic domain wall with a skyrmion-like building block is found as a function of the driving torques and an external magnetic field strength.
The analytical model is constructed for the description of the spin wave propagation through a system consisting of two ferromagnets without and with the Dzyaloshinskii–Moriya interaction, separated by a flat interface. The dependences of transmission and reflection coefficients of spin wave are found as a function of Dzyaloshinskii-Moria constant which is known to be strongly temperature dependent, tending to a significant increase at low temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
