In this article, we review the history, current status, physical mechanisms, experimental methods, and applications of nonlinear magneto-optical effects in atomic vapors. We begin by describing the pioneering work of Macaluso and Corbino over a century ago on linear magneto-optical effects (in which the properties of the medium do not depend on the light power) in the vicinity of atomic resonan...

The effects of nanostructuration on the magneto-optic properties of ultrathin monocrystalline iron films grown on MgO ~001! are investigated through the magneto-optic coefficients, which have a linear and quadratic dependence on the magnetization. The photon energy dependence of such magneto-optic coefficients is determined by measuring the relative variations of the reflectivity (DRpp /Rpp) fo...

A brief review is given of topics relating to dynamical processes arising in nonlinear interactions between light and resonant systems (atoms or molecules) in the presence of a magnetic field.

Coastal remote sensing applications are regularly confined to single image ‘snapshot’ approaches which do not resolve the dynamic processes in the required temporal resolution. This paper reports the results of a project in which the dynamics of tidal sedimentation were monitored by multi-temporal airborne remote sensing in 10 minute time steps. The radiance data was then converted to estimates...

This research aims to provide a unique perspective on energy harvesting from ear canal dynamic motion that can be used to power electronic in-ear devices. Two micro-power generators are presented: one of them has a miniature hydro-electromagnetic core and another one is composed of a micro piezo film sheet in shape of a ring. The experimental results will show that 1.2μW and 0.2μW could be succ...
