Entropy-driven order in an array of nanomagnets
Hilal Saglam, Ayhan Duzgun, Aikaterini Kargioti +14
Long-range ordering is typically associated with a decrease in entropy. Yet, it can also be driven by increasing entropy in certain special cases. We demonstrate that artificial sp…
Magnetic microscopy and simulation of strain-mediated control of magnetization in Ni/PMN-PT nanostructures
Ian Gilbert, Andres C. Chavez, Daniel T. Pierce +4
Strain-mediated thin film multiferroics comprising piezoelectric/ferromagnetic heterostructures enable the electrical manipulation of magnetization with much greater efficiency tha…
Direct Visualization of Memory Effects in Artificial Spin Ice
Ian Gilbert, Gia-Wei Chern, Bryce Fore +4
We experimentally demonstrate that arrays of interacting nanoscale ferromagnetic islands, known as artificial spin ice, develop reproducible microstates upon cycling an applied mag…
Perpendicular Magnetization and Generic Realization of the Ising Model in Artificial Spin Ice
Sheng Zhang, Jie Li, Ian Gilbert +11
We have studied frustrated kagome arrays and unfrustrated honeycomb arrays of magnetostatically-interacting single-domain ferromagnetic islands with magnetization normal to the pla…
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…
