One of the exciting applications of CO₂-induced magnetism changes is in the field of gas sensing. Sensors that can detect the presence and concentration of CO₂ are crucial for environmental monitoring, industrial processes, and even healthcare. Magnetic materials that change their properties in the presence of CO₂ could lead to the development of highly sensitive and selective gas sensors. In addition, it opens the door to a range of novel functional devices. For instance, such materials could be used in information storage systems, where data could be written or erased in response to CO₂ exposure. Finally, it is also noteworthy that the use of CO₂ to alter magnetism also aligns with global environmental goals, which may contribute to the efforts towards achieving carbon neutrality and managing green-house gas emissions.
