Room temperature magnetization curves of Cox(Al2O3)1−x thin films with (a) , and 0.49. (b) curve extracted partly in a range ±0.3 T for the case of Co-27 at% thin film presents a narrow hysteresis loop with ~ 8.6 mT and very small remanence. (c) A small hysteresis loop with ~ 2 mT and ratio () ~ 0.35 for the case of Co-49 at% thin film.
