Název v původním jazyce

Magneto-optical properties of 40 nm thick textured La2/3Sr1/3MnO3 thin films integrated on silicon via a Ca2Nb3O-10 nanosheet layer

Popis výsledku v původním jazyce

We demonstrate the possibility of growing textured La2/3Sr1/3MnO3 (LSMO) thin films on silicon substrates with magneto-optical and optical properties comparable to high-quality epitaxial layers grown on bulk SrTiO3 (STO). The pulsed laser deposition growth of LSMO is achieved by a two-dimensional nanosheet (NS) seed layer of Ca2Nb3O 10 (CNO) inducing epitaxial stabilization of LSMO films. The resulting 40 nm thick layer possesses a higher Curie temperature and a lower overall magnetization than an LSMO layer with a similar thickness on STO. Spectra of the full permittivity tensor were calculated from optical and magneto-optical measurements. Spectral dependencies of both the diagonal and off-diagonal elements share many similarities between the LSMO/NS/Si and LSMO/STO samples. These similarities indicate comparable electronic structures of the layers and demonstrate comparable optical quality of textured LSMO on NS/Si and epitaxial LSMO on STO.
