Electrical tuning of magnetism is crucial for developing fast, compact, ultra-low power electronic devices. Multiferroics offer significant potential due to their ability to control magnetic via an electric field through magnetoelectric coupling, especially in layered ferroelectric/ferromagnet heterostructures. A key challenge is achieving reversible and stable switching between distinct magnetic states using a voltage control. In this work, we present ferroelectric tuning of room-temperature magnetism in a 2D layered ferromagnet. The energy-efficient control consumes less than 1 fJ per operation which is normally in the order of several aJ, resulting in a ~43% change in magnetization. This tunable multiferroic interface and associated devices provide promising opportunities for next-generation reconfigurable communication systems, spintronics, sensors and memories.
