Factorizing magnetic fields triggered by the Dzyaloshinskii–Moriya interaction: Application to magnetic trimers

摘要: Abstract This work examines the entanglement and correlation state between assembled spins of a magnetic trimer by using specific heat C M as thermal observable critical fields factorization fingerprints. We show that (Cr 7 Ni) 2 Cu function temperature external field becomes quantifiable quantity when Dzyaloshinskii–Moriya (DM) interaction is considered. Such characterized at which bipartite density matrices display an abrupt change factorable entangled states. In magnets well in trimers with local S ≠ 1 DM shifts factorizing to regimes where they could be detected measurements.
