Three-dimensional modulated spin liquid model applied to URu2Si2

We have developed a three-dimensional version for the modulated spin liquid in a body-centered tetragonal lattice structure to describe the hidden order observed in URu2Si2 at T-0 approximate to 17.5 K. This second-order transition is well described by our model and confirms our earlier hypothesis. The symmetry of the modulation is minimized for Q equivalent to ( 1,1,1). We assume a linear variation of the interaction parameters with the lattice spacing and our results show good agreement with uniaxial and pressure experiments.
