High TC ferromagnetism was enabled through vertical epitaxy of the SSMO matrix with embedded, stiff, ?40 nm Sm2O3 nanopillars giving a c/a ratio close to 1 in the SSMO. In contrast, bulk and single phase SSMO films of the same composition have much stronger tetragonal distortion, the bulk having c/a >1 and the films having c/a <1, both of which give rise to antiferromagnetic coupling. The work demonstrates a unique and simple route to creating ferromagnetic insulators for spintronics applications where currently available ferromagnetic insulators are either hard to grow and/or have very low TC. © 2016 The Royal Society of Chemistry. | Source Title: | Nanoscale | URI: | https://scholarbank.nus.edu.sg/handle/10635/182481 | ISSN: | 2040-3364 | DOI: | 10.1039/c6nr01037g | Rights: | Attribution 4.0 International |
