Abstract
Buffer-free, highly textured (0 0 1) oriented CeCo5 thin films showing perpendicular magnetic anisotropy were synthesized on (0 0 1) Al2O3 substrates by molecular beam epitaxy. Ce exists in a mixture of Ce3+ and Ce4+ valence states as shown by X-ray photoelectron spectroscopy. The first anisotropy constant, K1, as measured by torque magnetometry was 0.82â¯MJ/m3(8.2Ã106erg/cm3). A maximum coercivity of 5.16â¯kOe with a negative temperature coefficient of â0.304%Kâ1 and a magnetization of 527.30â¯emu/cm3 was measured perpendicular to the film plane at 5â¯K. In addition, a large anisotropy of the magnetic moment of 15.5% was observed. These magnetic parameters make CeCo5 a potential candidate material for spintronic and magnetic recording applications.
