ABSTRACT
A promising generation of extremely low frequency magnetic field sensors, based on multilayer composites (MLCs) of magnetostrictive Terfenol-D (Tb1-xDyxFe2-y) and piezoelectric Pb(Mg1/3Nb2/3)O3–PbTiO3, has been developed. Our MLC magnetoelectric sensor presently shows a limit in (i) working frequency of ∼5×10-3 Hz; and (ii) magnetic field sensitivity of 10-7, 10-9, and 10-11 T for frequencies of f=10-2, 1, and 102 Hz, respectively. The results open up possibilities for sensitive low frequency passive magnetic anomaly detection.

    People on trains can be exposed to static and alternating magnetic fields which are higher than background levels in most homes and many workplaces. Quantification of such exposure may be of interest for epidemiological purposes but it is also important to ensure that exposure guidelines are...

    A method for optimizing the design and construction of a Zeeman slower coil is presented. Unlike traditional designs, the measured magnetic field profile very accurately matches the desired field profile, enabling significant advantages for loading a magneto-optic trap.
