For advanced applications in modern industry it is very important to reduce\nthe volume of ferroelectric nanoparticles without serious deterioration of\ntheir polar properties. In many practically important cases fixed volume\n(rather than fixed size) corresponds to realistic technological conditions of\nnanoparticles fabrication. The letter is focused on the theoretical study of\nthe behavior of ferroelectric polarization, paramagnetoelectric coefficient and\nphase diagrams of semi-ellipsoidal nanoparticles with fixed volume V. Our\napproach combines the Landau-Ginzburg-Devonshire phenomenology, classical\nelectrostatics and elasticity theory. Our results show that the size effects of\nthe phase diagrams and polarization of semi-ellipsoidal BiFeO3 nanoparticles\nnontrivially depends on V. These findings provide a path to optimize the polar\nproperties of nanoparticles by controlling their phase diagrams at a fixed\nvolume.\n
