Magnetic multipole analysis of kagome and artificial spin-ice dipolar arrays
Magnetic multipole analysis of kagome and artificial spin-ice dipolar arrays
We analyze an array of linearly extended monodomain dipoles forming square and kagome lattices. We find that its phase diagram contains two (distinct) finite-entropy kagome ice regimes---one disordered, one algebraic---as well as a low-temperature ordered phase. In the limit of the islands almost touching, we find a staircase of corresponding …
