Experimental determination of the magnetic interactions of frustrated Cairo pentagon lattice materials

Manh Duc Le, Elisa M. Wheeler, Jaehong Jeong +14

We present inelastic neutron scattering measurements of the Cairo pentagon lattice magnets Bi${}_2$Fe${}_4$O${}_9$ and Bi${}_4$Fe${}_5$O${}_{13}$F, supported by high field magnetisation measur…
