TLDR
In this article, it was proposed that the distortion arises from a Jahn Teller splitting of an accidently degenerate pair of low lying Dy3+ doublets, which is correlated with the direction of principal g value and can be influenced by applied magnetic fields.About:

Co-operative Jahn-Teller effects
G A Gehring,K A Gehring +1 more
TL;DR: The co-operative Jahn-Teller effect is a phase transition which is driven by the interaction between localized orbital electronic states and the crystal lattice as mentioned in this paper, and the possible origins, symmetries and properties of the electron-lattice interactions and how they lead to possible hamiltonians for the coupled system are discussed.

Ising model in a transverse field. I. Basic theory
TL;DR: In this article, a brief review of the spin-iIsing model in a transverse field provides a useful description (insulating magnetic systems, order-disorder ferroelectrics, cooperative Jahn-Teller systems and other systems with 'pseudo-spin'- phonon interactions).

Brillouin scattering, ultrasonic and theoretical studies of acoustic anomalies in crystals showing Jahn-Teller phase transitions
TL;DR: In this article, the elastic constants of DyVO4 and TbVO4 were measured at 14 and 34 K respectively and anomalously at the transition temperature TD, and the frequency dependence of these elastic constants was explained using both thermodynamic and microscopic theories.

Ferromagnetism in lithium holmium fluoride-LiHoF4. I. Magnetic measurements
TL;DR: In this paper, magnetic susceptibility measurements on LiHoF4 show that this compound undergoes a transition to a ferromagnetic state below Tc=1.53K, with the Ising-like Ho3+ moments oriented along the crystallographic c-axis.

Thermal and magnetic properties of ternary mixed Ising nanoparticles with core–shell structure: Effective-field theory approach
Ersin Kantar,Mustafa Keskin +1 more
TL;DR: In this article, a ternary Ising spins (1/2, 1, 3/2) model was proposed to investigate the thermal and magnetic properties of magnetic nanoparticles with core-shell structure within the framework of the effective field theory with correlations.
