Magnetic transport measurements of epitaxial SmCo₅ in pulsed magnetic fields — •Evelyn Stilp, Alexander Kauffmann, Marietta Seifert, Jens Freudenberger, Volker Neu, Nadejda Kozlova, and Ludwig Schultz — IFW Dresden, Institute for Metallic Materials, Helmholtzstr. 20, 01069 Dresden, Germany

SmCo₅ is a hard ferromagnetic material with a high Curie temperature around 800^∘C and a high coercivity of 3T. With the help of a Quantum Design PPMS vibrating sample magnetometer magnetic properties were already measured. Hence an anisotropy field of 28T was calculated [1]. The epitaxial SmCo₅ thin films were prepared by pulsed laser deposition on Cr buffered MgO(110) [2]. Hall measurements of SmCo₅ thin films will be presented.
