History Dependent Phenomena in the Transverse Ising Ferro-Glass: the Free Energy Landscape
In this paper the authors investigate the relationship between glassy and ferromagnetic phases in disordered Ising ferromagnets in the presence of transverse magnetic fields, {Lambda}. Iterative mean field simulations probe the free energy landscape and suggest the existence of a glass transition line in the {Lambda}, temperature T plane well within the ferromagnetic phase. New experimental field-cooled and zero-field-cooled data on LiHo{sub x} Y{sub 1{minus}x}F{sub 4} provide support for our theoretical picture.
