Oxygen defects like nanopillars enhanced magnetic and magnetooptical response of STF films
Toyohashi University of Technology researchers have found that nanoscale pillar-shaped distribution of iron in strontium titanate changes its magnetic and magnetooptical response drastically in cooperation with researchers at Myongji University, Harbin Institute of Technology, Massachusetts Institute of Technology, Universidad Técnica Federico Santa María, University of California, San Diego, and Trinity College Dublin. Surprisingly, the polycrystalline film on the silicon substrate showed stronger magnetism than a single crystalline film.
