Elastic and Acoustic Properties of Heavy Rare-Earth Metals
In this paper, ultrasonic properties like ultrasonic attenuation, sound velocities, acoustic coupling constants and thermal relaxation time have been studied in hexagonal structured metals Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er) and Thulium (Tm) along unique axis at room temperature. For the evaluations of ultrasonic properties, secondand thirdorder elastic con...
متن کاملPreparation of rare earth metals
The production of over 400 grams of pure gadolinium metal by reduction of the anhydrous chloride by calcium in tantalum vessels is described; yields were over 97%. The use of the same techniques in an attempt to prepare yttrium metal were partially successful.
متن کاملFirst-principles study of spin-disorder resistivity of heavy rare-earth metals: Gdâ•fiTm series
First-principles study of spin-disorder resistivity of heavy rare-earth metals: Gd–Tm series" (2012). Kirill Belashchenko Publications. 11. Electrical resistivity of heavy rare-earth metals has a dominant contribution from thermal spin-disorder scattering. Here this spin-disorder resistivity is calculated for the Gd-Tm series of metals in the paramagnetic state. Calculations are performed withi...
متن کاملDipolar excitations at the LIII x-ray absorption edges of the heavy rare-earth metals.
We report measured dipolar asymmetry ratios at the LIII edges of the heavy rare-earth metals. The results are compared with a first-principles calculation and excellent agreement is found. A simple model of the scattering is developed, enabling us to reinterpret the resonant x-ray scattering in these materials and to identify the peaks in the asymmetry ratios with features in the spin and orbit...
