The early evolution of the Earth–Moon system prescribes tidal environment Hadean Earth and holds key to formation mechanism Moon its thermal evolution. Estimating state by backtracking from present, however, suffers substantial uncertainties associated with ocean tides. Tidal during solidification Earth’s magma ocean, on other hand, has potential provide robust constraints before appearance a w...

Rapid-solidification method was applied to make Fe-15at%Ga and Fe-17at%Ga ribbons of 100 μm thickness. These ribbons have large magnetostriction of 270 ppm, where the coercive force exhibits a maximum value. The phenomenon is related to special metallic texture, that is, the ribbon has strongly [001]-oriented textured fine columnar microstructure with grain size of 2~5 μm. The ribbon has little...
