Van der Waals materials with ferromagnetic properties have attracted recent interest because of their promise to enable combination of materials with atomically sharp interfaces, facilitating spin transport and spin injection across these interfaces.The discovery of ferromagnetic ordering to persist to the twodimensional (2D) limit for Cr2Ge2Te6[1] and CrI3[2] has sparked interest of 2D ferromagnetism and their potential for fundamentally new magnetic van der Waals heterostructures and spintronics applications.However, these materials have been exfoliated from bulk and are not easily processible for applications.A bottom up synthesis by direct growth is required to integrate different materials for practical applications and to enable detailed characterization of magnetic interfaces.
