Abstract: 
A circle pattern is an embedding of a planar graph in which each face is inscribed in a circle. I will define and prove magnetic criticality of a large family of Ising models on planar graphs whose dual is a circle pattern. The new construction includes as a special case the critical isoradial Ising models of Baxter.
