## Description

- description: The integration of magnetic material with semiconductors has been fertile
    ground for fundamental science as well as of great practical interest toward the
    seamless integration of information processing and storage. We create van der
    Waals heterostructures formed by an ultrathin ferromagnetic semiconductor CrI3
    and a monolayer of WSe2. We observe un- precedented control of the spin and valley
    pseudospin in WSe2, where we detect a large magnetic exchange field of nearly
    13 T and rapid switching of the WSe2 valley splitting and polarization via flipping
    of the CrI3 magnetization. The WSe2 photoluminescence intensity strongly depends
    on the relative alignment between photoexcited spins in WSe2 and the CrI3 magnetization,
    because of ultrafast spin-dependent charge hopping across the heterostructure
    interface. The photoluminescence detection of valley pseudospin provides a simple
    and sensitive method to probe the intriguing domain dynamics in the ultrathin
    magnet, as well as the rich spin interactions within the heterostructure.
