The lateral shift of an optical beam undergoing Brillouin light scattering by a spin wave propagating along the interface between magnetic and dielectric media (Damon-Eshbach configuration) in total internal reflection geometry is studied theoretically. Linear quadratic magneto-optic terms polarization are taken into account. It shown that depends on ( s - or p -) state scattered electromagneti...

We describe techniques for creating long-lived magneto-optical and magnetostatic traps for neutral atoms. These traps exist in a sealed cryogenic environment with a temperature near 4 K, where the background gas pressure can be extremely low. To date we have observed cesium magneto-optical traps with background-limited lifetimes in excess of 1 h, and magnetostatic traps with lifetimes of nearly...

We investigate the competing effects of interlayer exchange coupling and magnetostatic coupling in the magnetic heterostructure ([Co/Pt]/NiO/[Co/Pt]) with perpendicular magnetic anisotropy (PMA). This particular heterostructure is unique among coupled materials with PMA in directly exhibiting both ferromagnetic and antiferromagnetic coupling, oscillating between the two as a function of spacer ...

Abstract This paper presents a system-level efficiency analysis, rapid design methodology, and numerical demonstration of efficient sub-micron, spin-wave transducers in microwave system. Applications such as Boolean spintronics, analog spin-wave-computing, magnetic circuits are expected to benefit from this analysis approach. These applications have the potential provide low-power, paradigm alt...

fe49co33ni18 nanowire arrays (175 nm in diameter and lengths ranging from 5 to 32μm) were fabricated into nanopores of hard-anodized aluminum oxide templates using pulsed ac electrodeposition technique. hysteresis loop measurements indicated that increasing the length decreases coercivity and squareness values (from 274 oe and 0.58 to200 oe and 0.105, respectively), indicating the increase in m...

Artificial spin ices are periodic arrangements of interacting nanomagnets which allow investigating emergent phenomena in the presence geometric frustration. Recently, it has been shown that artificial can be used as building blocks for creating functional materials, such magnonic crystals. We investigate magnetization dynamics a system exhibiting anisotropic magnetostatic interactions owing to...
