Large Enhancement of Ferromagnetism under a Collective Strong Coupling of YBCO Nanoparticles

[Image: see text] Light–Matter strong coupling in the vacuum limit has been shown, over the past decade, to enhance material properties. Oxide nanoparticles are known to exhibit weak ferromagnetism due to vacancies in the lattice. Here we report the 700-fold enhancement of the ferromagnetism of YBa(...

description [Image: see text] Light–Matter strong coupling in the vacuum limit has been shown, over the past decade, to enhance material properties. Oxide nanoparticles are known to exhibit weak ferromagnetism due to vacancies in the lattice. Here we report the 700-fold enhancement of the ferromagnetism of YBa(2)Cu(3)O(7–x) nanoparticles under a cooperative strong coupling at room temperature. The magnetic moment reaches 0.90 μ(B)/mol, and with such a high value, it competes with YBa(2)Cu(3)O(7–x) superconductivity at low temperatures. This strong ferromagnetism at room temperature suggest that strong coupling is a new tool for the development of next-generation magnetic and spintronic nanodevices.
