The results represent an important step forward for the design of spin-filtering tunnel barriers based on LaCoO3
The Canadian journal 'Advances in Engineering' highlights a recent paper published by CiQUS researchers in 'Nano Letters' (Nano Lett., 2016, 16, 1736), which represents an important step forward for the design of spin-filtering tunnel barriers based on LaCoO3
In this work the research staff, led by Rivadulla Fernández group, has explored the magnetic behavior of LaCoO3 grown on a buffer layer of half-metallic FM La2/3Sr1/3MnO3 (LSMO) over SrTiO3 (STO).
The results confirmed a complete suppression of FM in LaCoO3 grown on top of a buffer layer of LSMO on STO, in spite of a lattice deformation identical to that achieved by direct growth on STO.
On the basis of this precise control over the magnetic properties of LaCoO3, this research group designed a multilayered structure to achieve independent rotation of the magnetization in ferromagnetic insulating LaCoO3 and half-metallic ferromagnet LSMO.
