A promising superparamagnetic nanomagnetite dipped with Gd was synthesized for possible medical applications. Its size and morphology are independent of Gd content ranging from 1 to 5%. Gadolinium (III) replaced Fe(III) in the lattice. The sizes of Gd-doped nanoparticles ranged from 5 to 50 nm and exhibited a pure magnetite mineralogical phase.
一种浸渍钆（Gd）的、有前景的超顺磁性纳米磁铁矿被合成出来，用于可能的医学应用。其尺寸和形态与钆含量（1%至5%）无关。钆（III）在晶格中取代了铁（III）。钆掺杂纳米颗粒的尺寸在5至50纳米之间，并呈现出纯磁铁矿矿物相。
