“…The observed XRD peaks around at 2θ are 19.68°, 31.89°, 37.7°, 39.29°, 45.5°, 55.89° and 59.11°, corresponding to (111), (220), (311), (222), (400), (422) and (511) are crystal planes of cubic Co 3 O 4 , respectively. The XRD peaks are in good agreement with the JCPDS data (JCPDS 09–0 18) [ 69 , 70 ]. In addition, it was observed that the intensity of the peaks corresponding to the (111), (222), (422), and (511) planes were decreased, while the peaks corresponding to the (220) and (311) increased again.…”

“…3. The small magnetic moment in samples originates from cobalt oxide and is also attributed to uncompensated surface spins, nite size effects, oxygen vacancies, and thin structures 23,24 . As it is clear from Fig.…”
Magnetic anisotropy plays an important role in ultrathin structures and two-dimensional materials and influences their magnetoresistance (MR) response. Here, the effects of the two-dimensional WS2 layer on the structural and magnetic properties of cobalt (Co) thin film are investigated in a Co/WS2 bilayer fabricated on Si (100) substrates. The Co layer grown on the WS2 layer formed a crystal structure whereas that individual Co isolated layer is amorphous. Both prepared samples show an out-of-plane easy axis while their in-plane anisotropy is different. The magnetic hysteresis loop and MR measurements show that there is an in-plane easy axis in the Co/WS2 bilayer due to the crystallinity formation of Co grown on WS2 which is not observed in Co isolated layer. Our results represent an interface control of anisotropy in two dimensional structures.
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.
