Abstract: We consider an infinite-range spherical p -spin glass model with an additional r -spin ferromagnetic interaction, both statically using a replica analysis and dynamically via a generating functional method. For r > 2 we find that there are first-order transitions to ferromagnetic phases. For r < p there are two ferromagnetic phases, one non-glassy replica symmetric and one exhibiting glassy one-step replica symmetry breaking and ageing; whereas for r ⩾ p only the replica symmetric phase exists.
