Energy minimization and AC demagnetization in a nanomagnet array
X. Ke, J. Li, C. Nisoli +5
We study AC demagnetization in frustrated arrays of single-domain ferromagnetic islands, exhaustively resolving every (Ising-like) magnetic degree of freedom in the systems. Althou…
Demagnetization Protocols for Frustrated Interacting Nanomagnet Arrays
R. F. Wang, J. Li, W. McConville +8
We report a study of demagnetization protocols for frustrated arrays of interacting single domain permalloy nanomagnets by rotating the arrays in a changing magnetic field. The mos…
Ground state lost but degeneracy found: the effective thermodynamics of artificial spin ice
Cristiano Nisoli, R. F. Wang, Jie Li +4
We analyze the rotational demagnetization of artificial spin ice, a recently realized array of nanoscale single-domain ferromagnetic islands. Demagnetization does not anneal this m…
Artificial "spin ice" in a geometrically frustrated lattice of nanoscale ferromagnetic islands
R. F. Wang, C. Nisoli, R. S. Freitas +8
We report an artificial geometrically frustrated magnet based on an array of lithographically fabricated single-domain ferromagnetic islands. The islands are arranged such that the…
