Ruderman–Kittel–Kasuya–Yosida–like Ferromagnetism in Nonmetal Doped Y 2 O 3
AbstractA wide-gap semiconductor of Yttria (Y2O3) doped with nonmetal elements (B, C, and N) are investigated by using the first-principles method. We mainly discuss the exchange coupling between two dopants and find that the exchange coupling in current cases are sensitive to the B-B, C-C, and N-N distance. Unitary ferromagnetic (FM) and antiferromagnetic (AFM) states have been observed in the two-B-doped and two-N-doped Y2O3 structures, respectively. Surprisingly, as the C-C distance increases, a transformation between FM and AFM has been found, which shows an RKKY-like interaction due to the p-d hybridization between the C dopant and intrinsic Y atoms.Keywords: Y2O3ferromagneticRKKY-like interactionDFT calculations Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingWe thank the National Supercomputer Center in Shenzhen.

期刊介绍：
Integrated Ferroelectrics provides an international, interdisciplinary forum for electronic engineers and physicists as well as process and systems engineers, ceramicists, and chemists who are involved in research, design, development, manufacturing and utilization of integrated ferroelectric devices. Such devices unite ferroelectric films and semiconductor integrated circuit chips. The result is a new family of electronic devices, which combine the unique nonvolatile memory, pyroelectric, piezoelectric, photorefractive, radiation-hard, acoustic and/or dielectric properties of ferroelectric materials with the dynamic memory, logic and/or amplification properties and miniaturization and low-cost advantages of semiconductor i.c. technology.
