Two-dimensional (2D) magnetic materials have emerged as a promising platform for next-generation sensing technologies due to their atomic thickness, tunable magnetic properties, and compatibility with van der Waals heterostructures. Rapid progress in material discovery, synthesis, and device integration has expanded opportunities for compact, low-power, and highly sensitive sensor platforms. This review examines selected sensing mechanisms enabled by 2D magnetic materials, highlighting recent experimental advances and emerging device concepts. Current limitations and challenges such as environmental stability, scalability, and room-temperature operation are considered in the context of ongoing research efforts. By examining these approaches, this review aims to provide insight into the current development and potential of 2D magnetic materials for sensing technologies. This review is organized to first introduce the fundamental properties and challenges of 2D magnetic materials, followed by a survey of key sensing mechanisms and representative device implementations, and concludes with an outlook on future research directions.
