We demonstrate the synthesis of a novel nanoporous ordered face-centered tetragonal FePt (L1₀-FePt) compound by selective dissolution of an Fe₆₀Pt₁₀B₃₀ nanocomposite alloy, which consists of nanoscale L1₀-FePt and Fe₂B phases. The Fe₂B phase is selectively removed from the alloy by electrochemical etching in H₂SO₄ aqueous solution, while the preserved L1₀-FePt phase forms a uniform open bicontinuous interpenetrating ligament–channel structure with a ligament size of ∼15 nm. The nanoporous L1₀-FePt alloy possesses a high coercivity of 18.5 kOe.
