TL;DR: It is shown that the magnetic moments of single holmium atoms on a highly conductive metallic substrate can reach lifetimes of the order of minutes.
Journal ArticleDOI
Oxygen-vacancy-induced local ferromagnetism as a driving mechanism in enhancing the magnetic response of ferrites
C.E. Rodríguez Torres,G. A. Pasquevich,P. Mendoza Zélis,Federico Golmar,Silvia P. Heluani,Sanjeev K. Nayak,Waheed A. Adeagbo,Wolfram Hergert,Martin Hoffmann,Martin Hoffmann,Arthur Ernst,Pablo Esquinazi,S. J. Stewart +12 more
TL;DR: In this paper, the relevance of oxygen vacancies in the formation of local ferromagnetic coupling between Fe ions at octahedral sites in zinc ferrites was investigated, which gives rise to a ferrimagnetic ordering with the Curie temperatures above room temperature in an otherwise antiferromagnetic compound.
