Iron–platinum nanoparticle

<p>Iron–platinum nanoparticles (FePt NPs) are 3D <a href="/facts/Superlattices/nguy8U7X">superlattices</a> composed of an approximately equal atomic ratio of <a href="/facts/Iron/QK1JYy8E">Fe</a> and <a href="/facts/Platinum/qJC6lQf7">Pt</a>. Under standard conditions, FePt NPs exist in the <a href="/facts/Face-centered_cubic/92Co7BKM">face-centered cubic</a> phase but can change to a chemically ordered face-centered tetragonal phase as a result of <a href="/facts/Thermal_annealing/2AfoCE4X">thermal annealing</a>. Currently there are many synthetic methods such as water-in-oil <a href="/facts/Microemulsion/IJMquT3A">microemulsion</a>, one-step thermal synthesis with metal precursors, and exchanged-coupled assembly for making FePt NPs.[<i>unreliable source?</i>] An important property of FePt NPs is their <a href="/facts/Superparamagnetism/BpV9oe0w">superparamagnetic</a> character below 10 nanometers. The <a href="/facts/Superparamagnetism/BpV9oe0w">superparamagnetism</a> of FePt NPs has made them attractive candidates to be used as <a href="/facts/Magnetic_resonance_imaging/Vh9yG9qq">MRI</a>/<a href="/facts/X-ray_computed_tomography/NusPJ2S8">CT</a> scanning agents and a high-density recording material.
