DTU Engineers Compensated Ferrimagnet, Near-Invisible, Above Room Temperature

Summary

Story summary

DTU researchers created a compensated ferrimagnet that stays strong inside, appears nearly invisible outside, and works above room temperature.
The material couples chromium atoms with radical pyrazine molecules, generating opposing magnetic moments that nearly cancel externally.
Professor Kasper Steen Pedersen said the molecular design lets chemistry tune magnetic and electronic properties.
Neutron scattering and synchrotron radiation confirmed near-perfect compensation and stability across a wide temperature range.
