Low-field behavior of an X Y pyrochlore antiferromagnet: Emergent clock anisotropies

Using Er2Ti2O7 as motivation, we investigate finite-field properties of XY pyrochlore antiferromagnets. In addition to a fluctuation-induced six-fold anisotropy present in zero field, an external magnetic field induces a combination of two-, three-, and six-fold clock terms as a function of its orie...
