Abstract: MnSb nanoparticles with average lateral diameters 〈d〉 from 5 to 30 nm are synthesized on ultra thin silicon nitride covered Si(111) by codeposition of Mn and Sb. These MnSb particles possess sharp interfaces and a NiAs-type lattice. The Mn 2p x-ray absorption spectroscopy analysis shows broad line shapes due to the itinerant Mn 3d states. The particles with 〈d〉 =5 and 8.5 nm are superparamagnetic at room temperature, while those of 〈d〉 =15 and 30 nm exhibit ferromagnetic behavior. © 2007 American Institute of Physics.
