Interfacial magnetism in CaRuO3/CaMnO3 superlattices grown on (001) SrTiO3
We have studied epitaxially grown superlattices of CaRuO 3/CaMnO 3 as well as an alloy
film of CaMn 0.5 Ru 0.5 O 3 on (001) SrTiO 3 substrates. In contrast to previous experiments,
we have studied CRO/CMO superlattices with a constant CRO thickness and variable CMO
thickness. All superlattices exhibit Curie temperatures (TC) of 110 K. The saturated
magnetization per interfacial Mn cation has been found to be 1.1 μ B/Mn ion. The T C's of the
superlattices are much lower than the TC of the alloy film while the saturated magnetization …
