Dynamic control of transverse magnetization spot arrays

Origin of transverse magnetization in epitaxial Cu/Ni/Cu nanowire arrays

Transverse Mode Control and Switching in Gas Laser Arrays

Theoretical and experimental investigations of multiple transverse mode laser oscillation involving spatially varying gain and loss are carried out. The effect of gain and loss distribution on mode competition is analyzed. Numerical examples are given for a CO2 waveguide laser array. Experimental results of CO2 laser arrays are found to be consistent with the theory, and robust in-phase coupled...

dynamic coloring of graph

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...

Magnetization reversal in cobalt antidot arrays

We have carried out a detailed study of the magnetic switching in square lattice cobalt antidot arrays with periods ranging from 2 m down to 200 nm antidot size=antidot separation . Magneto-optical Kerr effect measurements show first a small change in the magnetization due to a reversible rotation of the magnetic spins in the antidot rows, followed by a large change due to reversal of the antid...

AC-driven quantum spins: resonant enhancement of transverse DC magnetization

Magnetic resonance effects have been long studied and used for various spectroscopic methods1–3. Timedependent external fields being an integral part of the physical setups, become also very interesting in their action when entering the field of spintronics and processing of quantum information. While the linear response of a system (probe) to external fields may be typically understood in a ra...
