“…[10][11][12][13] Especially interesting are doped BiFeO 3 materials which can strongly affect the structure and properties of bismuth ferrite. In particular, various morphologies of Ho-substituted BiFeO 3 were recently fabricated including thin films, [14][15][16][17] nanofilms, 18 nanoparticles, 19,20 nanopowders, 21,22 nanocrystalline BFO, 23 bulk and polycrystalline ceramics. [24][25][26][27] In this work, we investigated the influence of doping BiFeO 3 with Ho.…”
