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…
