The authors investigate the microscopic mechanisms at play in the magnetization process of ytterbium gallium garnet, a frustrated magnetic material, which has recently gained interest for its enhanced magnetocaloric properties. The combination of susceptibility and specific heat measurements with neutron scattering experiments and theoretical calculations allows one to draw a comprehensive picture of the system, where the role of dipole-dipole...
