  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.
