Direct entropy determination and application to artificial spin ice
Paul E. Lammert, Xianglin Ki, Jie Li +4
From thermodynamic origins, the concept of entropy has expanded to a range of statistical measures of uncertainty, which may still be thermodynamically significant. However, labora…
Magnetization states and switching in narrow-gapped ferromagnetic nanorings
Jie Li, Sheng Zhang, Chris Grigas +4
We study permalloy nanorings that are lithographically fabricated with narrow gaps that break the rotational symmetry of the ring while retaining the vortex ground state, using bot…
Magneto-optical Kerr Effect Studies of Square Artificial Spin Ice
K. K. Kohli, Andrew L. Balk, Jie Li +6
We report a magneto-optical Kerr effect study of the collective magnetic response of artificial square spin ice, a lithographically-defined array of single-domain ferromagnetic isl…
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…
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…
