What is it about?

Usually, the manganite films with tetragonal distortion show both the out-of-plane magnetic anisotropy (OMA) and the in-plane magnetic isotropy. However, the LBMO-5 film exhibits not only the OMA but also the in-plane magnetic anisotropy (IMA) along [010]f and [100]f directions. We attribute this new observation of the IMA to the in-plane structural anisotropy.

Why is it important?

Because the origin of the IMA is not consistent with the previous reports, it is a novel magnetic anisotropy. The effect of the in-plane structural anisotropy on magnetic properties is interesting and deserves studies. It is useful for developing in-plane magnetic sensor devices.

Perspectives

The observation of the IMA is very interesting and important for manganite-based film devices, and our studies suggest that the in-plane crystallization can control the IMA of the film.
