Emergent antiferromagnetism of YTiO3 in YTiO3-CaTiO3 superlattices

Abstract

Transport and magnetoresistance measurements are performed on metallic, high-carrier density YTiO3-CaTiO3 superlattices as a probe towards the investigation of an emergent magnetic order of YTiO3. On varying the thickness of YTiO3 while keeping the CaTiO3 layer thickness constant in the superlattices, a low-temperature upturn in sheet-resistance, a non-Fermi liquid-like charge transport and positive magnetoresistance are observed. Analyses of the origin of such effects suggest that a unique antiferromagnetic order is realized in the ultra-thin, epitaxially strained YTiO3 layers, which corroborates well with some recent theoretical predictions in this regard.
