Deposition of Magnetoelectric Ferrite Thin Films Using Multiple Targets Technique

The magnetoelectric (ME) effect has been detected in cobalt-doped M-type hexaferrite bulk. We have demonstrated that the hexaferrite films of the M-type exhibiting the ME effect can be deposited from single targets as well as multiple targets as in the alternating target laser ablation deposition te...

Description
Summary:The magnetoelectric (ME) effect has been detected in cobalt-doped M-type hexaferrite bulk. We have demonstrated that the hexaferrite films of the M-type exhibiting the ME effect can be deposited from single targets as well as multiple targets as in the alternating target laser ablation deposition technique. The corresponding ME coupling is sufficiently high at room temperature to allow for potential device applications α = 5.2 × 10 -9 m/s. The saturation magnetization value (4π M s ) of the film was measured to be 2000 G, consistent with a vibrating sample magnetometer and the ferromagnetic resonance measurement.
