The magnetic and transport properties of Fe3O4 films with a series of thicknesses are investigated. For the films with thickness below 15 nm, the saturation magnetization (Ms) increases and the coercivity decreases with the decrease in films’ thickness. The Ms of 3 nm Fe3O4 film is dramatically incr...
