TL;DR: Xu et al. as mentioned in this paper used magneto-optical Kerr effect microscopy to show that monolayer chromium triiodide (CrI3) is an Ising ferromagnet with out-of-plane spin orientation.

TL;DR: 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.

TL;DR: In this paper, the authors reported spontaneous circularly polarized photoluminescence in monolayer bulk chromium tri-iodide (CrI3) under linearly polarized excitation, with helicity determined by the magnetization direction.

TL;DR: In this article, a wide continuous tuning of the valley polarization and valley Zeeman splitting with small changes in the laser-excitation power in heterostructures formed by monolayer WSe2 and 2D magnetic chromium triiodide (CrI3) was demonstrated.

TL;DR: It is demonstrated that this hybrid nanosheet structure is capable of decoupling light absorption and carrier separation across the metal-MoS2 heterostructure leading to drastic quenching of recombination between photogenerated carriers in MoS2, as proven by absorptance, photoluminescence, and ultrafast pump-probe spectroscopy.
