This paper presents the structural and magnetic properties of La0.6Sr0.4MnO3 nanoparticles with sizes from 21 to 106nm, which have been prepared using the sol–gel method. The reduction of the nanoparticles׳ size tends to broaden the paramagnetic to ferromagnetic transition, as well as to promote magnetic hysteresis and a remarkable change on the magnetic saturation. In order to better understand the...
