Abstract

Layer-by-layer epitaxial growth of the pyrochlore magnet Tb₂Ti₂O₇ on the isostructural substrate Y₂Ti₂O₇ results in high-quality single crystal films of up to 60 nm thickness. Substrate-induced strain is shown to act as a strong and controlled perturbation to the exotic magnetism of Tb₂Ti₂O₇, opening up the general prospect of strain-engineering the diverse magnetic and electrical properties of pyrochlore oxides.

Funding

PLD deposition of the thin films was conducted by LB and with assistance from CMR at the Center for Nanophase Materials Sciences, which is a DOE Office of Science User Facility (CNMS2015-251). LB is supported by The Leverhulme Trust through the Early Career Fellowship program (ECF2014-284). DP acknowledges support from the EPSRC grant EP/K028960/1.
