Description
Ferrimagnetic materials have emerged as promising candidates for spintronic applications due to the ultrafast domain wall motion observed at the magnetization compensation point. Although there is an intrinsic explanation of this, the changes in the characteristics of the domain wall over this transition have not been observed. To probe these changes over the compensation point we measure domain walls in alloyed rare earth- transition metal ferrimagnets over varying temperature using the high resolution and high sensitivity scanning technique NV magnetometry. Revealing these changes would allow us to better engineer magnetic materials for future spintronic applications.
