Two-dimensional (2D) antiferromagnetic (AFM) semiconductors are promising components of opto-spintronic devices due to terahertz operation frequencies and minimal interactions with stray fields. However, the lack of net magnetization significantly limits the number of experimental techniques available to study the relationship between magnetic order and semiconducting properties. Here, they demonstrate conditions under which photocurrent spectroscopy can be employed to study many-body magnetic excitons in the 2D AFM semiconductor NiI.

- - Two-dimensional transition metal halides, like CrI, have interesting magnetic properties, but they deteriorate quickly in regular environments, making research and practical use challenging.
- - Researchers managed to improve the long-term stability of CrI by using an organic buffer layer (PTCDA) before applying alumina through a method called atomic layer deposition (ALD), preventing harmful chemical reactions.
- - This new setup not only maintains CrI's magnetic qualities down to a single layer but also enables the development of electronic devices like field-effect transistors and photodetectors, and allows for thermal conductivity analysis.
