Among other applications, nanoparticles of La1–xSrxMnO3 (LSMO) manganites are intensively investigated for the possible use in biomedicine, particularly as potential agents for magnetic resonance imaging and magnetically induced hyperthermia. High transverse relaxivities of the cell labelling agents based on the LSMO cores have been recently published by our group.1 Although magnetic and structural properties of the LSMO nanoparticles have been thoroughly described,2 no systematic study dealing with the influences of the composition and the size of the particles on the transverse relaxivity r2 has been published so far.
