Tuning magnetic frustration of nanomagnets in triangular-lattice geometry
Xianglin Ke, Jie Li, Sheng Zhang +3
We study the configuration of magnetic moments on triangular lattices of single-domain ferromagnetic islands, examining the consequences of magnetostatic interactions in this frust…
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…
Carbon Nanostructures as an Electromechanical Bicontinuum
Cristiano Nisoli, Paul E. Lammert, Eric Mockensturm +1
A two-field model provides an unifying framework for elasticity, lattice dynamics and electromechanical coupling in graphene and carbon nanotubes, describes optical phonons, nontri…
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…
