It is shown that the behavior of the samples with a low content of magnetic material is governed by a shape anisotropy of isolated nanomagnets, while those with a high content – shape anisotropy of a sample as a whole. Additionally, partial magnetic hysteresis loops are measured for the nanoparticles of lanthanum-strontium manganites. It is concluded that manganite nanoparticles display much higher magnetic anisotropy than bulk counterparts. The processes are discussed which underlie enhancement of magnetic anisotropy in substituted manganites upon a transition to nanoscale.   Product Description popup.authors Kravets Anatolii F Kuzmak Orest M Lytvynenko Yaryna M.
