Factors Determining Magnetic Homogeneity of CrTe2 Thin Films

Abstract: CrTe_x systems have been identified as promising platforms for van der Waals (vdW) material-based spintronics with their high Curie temperature and 2D ferromagnetism (FM). The development of devices, however, based on vdW systems requires the fabrication of high-quality thin films. Films of CrTe2 retain their FM characteristics down to a monolayer limit and have been shown tp exhibit emergent topological properties. However, these behaviors are very sensitive to stoichiometry and defects, and may not be intrinsic. To that end, we propose to examine with PNR a series of ZrTe2/CrTe2/Te multilayers with variable ZrTe2 thickness to determine the extent and consequences of oxygen migration from the Al2O3 substrate through the ZrTe2 buffer layer. Previous studies indicate that the magnetic behavior of the CrTe2 layer nearest the ZrTe2 interface is not consistent with other regions. The ultimate goal is to determine if there exists a correlation between the observed "topological" properties and observed structural and magnetic defects.
