Three-dimensional MEMS magnetometers with use of residual stresses in thin multilayers cantilevers are presented. Half-loop cantilevers based on Lorentz-force deflection convert magnetic flux in V ∆ changes, thanks to piezoresistive transducers mounted in Wheatstone bridge. Magnetic field in the order of 10 Gauss was measured with a sensitivity of 0.015 mV/Gauss. A Finite Element Model of the d...

Za model vodiËa i feromagnetske ploËe napravljen je 3D proraËun magnetskog polja pomoÊu integralnih jednadæbi za kvazistatiËki sluËaj. Usporeeni rezultati proraËuna i mjerenja dobro se slaæu. Pristup preko integralnih jednadæbi pokazuje se vrlo efi kasnim u prostoru u kojem se traæi polje daleko od izvora i u kojem nema puno razliËitih feromagnetskih materijala. Pri tome se pretpostavlja da su...

A frequency-tunable low phase noise magneto-acoustic resonator is developed on the base of a parallel-plate straight-edge bilayer consisting yttrium-iron garnet (YIG) layer grown substrate gallium-gadolinium garnet(GGG). When YIG/GGG sample forms an ideal parallel plate, it supports series high-quality-factor acoustic modes standing along plate thickness. Due to magnetostriction YIG ferromagnet...

as ferromagnetic alloys composed exclusively of non magnetic elements. However, the electrical properties of the alloys have not been studied in details. The purpose of the present report is to present our data on the electrical resistivity of an In-Heusler Cu2.0Mn0.94In1.0 single crystal. The purities of the elements used are 99.9% for electrolytic manganese, 99.9% for oxygen free copper plate...
