Implication

Experimental characterization reveals perpendicular anisotropy and large magnetoresistance in cobalt-platinum thin films, suggesting strong potential for advanced magnetic storage.

Key Points

To examine the magnetic anisotropy, magnetic moments, and electronic transport characteristics across a wide compositional range of crystalline cobalt-platinum thin films.
Synthesized crystalline CoxPt1−x thin films across atomic compositions ranging from x = 0.26 to 0.84 using radio-frequency sputtering.
Evaluated magnetic anisotropy and transport properties through magnetization measurements, Hall effect analysis, and anisotropic magnetoresistance testing.
Films displayed diverse magnetic anisotropy states, including perpendicular anisotropy at intermediate cobalt fractions.
The magnetic moment per formula unit increased upon dilution, consistent with an induced platinum moment of approximately 0.3 μB across all measured compositions.
Both the Hall effect and anisotropic magnetoresistance peaked prominently around an atomic fraction of x ≈ 0.4.
