Description
We present neutron scattering data on the hexagonal rare-earth diboride ErB$_2$. ErB$_2$ orders magnetically below T$_c$ = 14 K, where the magnetocrystalline anisotropy shows strong easy-plane characteristics, as established from measurements of the specific heat, ac susceptibility, magnetisation and electrical transport.
In order to investigate the magnetic structure we performed single-crystal neutron diffraction in zero and finite field as a function of temperature. We have also performed inelastic neutron scattering measurements, parts of which were done with the artificial intelligence assisted data collection strategy, ARIANE.
