Four definitions of magnetic permeability for periodic metamaterials
(Journal article; Peer reviewed, 2019)We state and compare four different definitions of magnetic permeability for periodic, artificial media, or metamaterials. The connections among them, and properties in general, are discussed in detail, including causality, ... -
Oxygen vacancies in the bulk and at neutral domain walls in hexagonal YMnO3
(Journal article; Peer reviewed, 2018)We use density functional calculations to investigate the accommodation and migration of oxygen vacancies in bulk hexagonal YMnO3, and to study interactions between neutral ferroelectric domain walls and oxygen vacancies. ...
