Abstract
The LiHoYF Ising magnetic material subject to a magnetic field, , perpendicular to the Ho Ising direction has shown over the past twenty years to be a host of very interesting thermodynamic and magnetic phenomena. Unfortunately, the availability of other magnetic materials other than LiHoYF that may be described by a transverse field Ising model remains very much limited. It is in this context that we use here mean-field theory to investigate the suitability of the Ho(OH), Dy(OH) and Tb(OH) insulating hexagonal dipolar Ising-like ferromagnets for the study of the quantum phase transition induced by a magnetic field, , applied perpendicular to the Ising spin direction. From our calculations we estimate the critical transverse field, , to destroy ferromagnetic order at zero temperature to be 4.35 T, 5.03 T and 54.81 T for Ho(OH), Dy(OH) and Tb(OH), respectively. We conclude from our calculations that Ho(OH) and Dy(OH), and their Y diamagnetically diluted variants, HoY(OH) and DyY(OH), are potentially interesting systems to study transverse-field induced quantum fluctuations effects in hard axis (Ising-like) magnetic materials.
