Tensile-Strain Dependent Spin States in Epitaxial LaCoO${}_3$ Thin Films

Y. Yokoyama, Y. Yamasaki, M. Taguchi +11

The spin states of Co${}^{3+}$ ions in perovskite-type LaCoO${}_3$, governed by complex interplay between the electron-lattice interactions and the strong electron correlations, still…
