In this paper we investigate the relationship between glassy and ferromagnetic phases in disordered Ising ferromagnets in the presence of transverse magnetic fields, \ensuremathΓ. Iterative mean-field simulations probe the free-energy landscape and suggest the existence of a glass transition as a function of \ensuremathΓ which is distinct from the Curie temperature. Experimental field-cooled and zero-field-cooled data on LiHoxY_1\ensuremath-xF4 provide support for our theoretical picture. Here as well we present a collection of theoretical predictions for future experiments.
