Following the recent observation of anomalous Hall effect in antiferromagnetic hexagonal MnTe thin films, related phenomena at finite frequencies have come into focus. Magnetic circular dichroism (MCD) is key material property here. In X‐ray range, MCD has already been demonstrated and used to visualize domains via photoemission electron microscopy. Herein, optical range reported on its microscopic mechanism discussed.
Influence of epitaxial strain and oxygen octahedra rotations on electronic structure ${\mathrm{La}}_{2/3}{\mathrm{Sr}}_{1/3}{\mathrm{MnO}}_{3}$ ultrathin films was systematically studied. The investigated were grown by pulsed laser deposition four different substrates: cubic (001)-oriented ${\mathrm{LaAlO}}_{3}$, (001) ${({\mathrm{LaAlO}}_{3})}_{1/3}{({\mathrm{Sr}}_{2}{\mathrm{AlTaO}}_{6})}_{2/3}$, ${\mathrm{SrTiO}}_{3}$, orthorhombic (110) ${\mathrm{DyScO}}_{3}$, providing a broad range...
Following the recent observation of anomalous Hall effect in antiferromagnetic hexagonal MnTe thin films, related phenomena at finite frequencies have come into focus. Magnetic circular dichroism (MCD) is key material property here. In x-ray range, XMCD has already been demonstrated and used to visualise domains via photoemission electron microscopy (PEEM). Here we report on MCD optical range discuss its microscopic mechanism.
We demonstrate the possibility of growing textured La$_{2/3}$Sr$_{1/3}$MnO$_3$ (LSMO) thin films on silicon substrates with magneto-optical and optical properties comparable to high-quality epitaxial layers grown bulk SrTiO$_3$ (STO). The pulsed laser deposition growth LSMO is achieved by a two-dimensional nanosheet (NS) seed layer Ca$_2$Nb$_3$O$_{10}$ (CNO) inducing stabilization films. resulting possess higher Curie temperature lower overall magnetization than samples STO.
