Abstract

A room-temperature ferromagnetic behavior was observed in a ternary layered-Cu₂MoS₄ nanosheet. Both the coercivity and magnetization saturation increased with a decrease in temperature. The electron paramagnetic resonance spectroscopy confirmed a high g value. Combined with atomic structural observations, our first principle calculations revealed that the ferromagnetism originated from the edged molybdenum atoms.
