Description:
Author(s): Sebastian Gliga, Attila Kákay, Laura J. Heyderman, Riccardo Hertel, and Olle G. Heinonen We study degeneracy and entropy in the ground state of artificial square ice. In theoretical models, individual nanomagnets are typically treated as single spins with only two degrees of freedom, leading to a twofold degenerate ground state with intensive entropy and thus no zero-point entropy. Here… [Phys. Rev. B 92, 060413(R)] Published Wed Aug 26, 2015
