Strong Dependence of Magnetic Damping and Magnetization on Deposition Temperature in Highly Magnetostrictive NiZnAl Ferrite Thin Films

Zn/Al co-doped nickel ferrites (NZAFO) with ultralow magnetic damping and large magnetostriction are critically needed for use in tunable spintronic devices and dissipationless quantum computation. However, the growth of epitaxial NZAFO thin films with optimized properties is difficult due to their tendency to form anti-site defects and antiphase boundaries, even on isostructural spinel substrate....
