Field-induced quasi-bound state within the two-magnon continuum of a square-lattice Heisenberg antiferromagnet
F. Elson, M. Nayak, A. A. Eberharter +14
Quantum magnets in two dimensions display strong quantum interaction effects even when magnetically ordered. Using the metal-organic framework material CuF(DO)(pyz), we…

Refined spin Hamiltonian on the Cairo pentagonal lattice of Bi2Fe4O9
Emma Y. Lenander, Frida B. Nielsen, Jakob Lass +14
The frustrated magnet Bi2Fe4O9 has been reported to exhibit complex spin dynamics coexisting with conventional spin wave excitations. The magnetic Fe3+ (S = 5/2) ions are arranged…
