Electronic properties of alpha-UH3 stabilized by Zr

Popis výsledku v původním jazyce

Pure hydride of the alpha-UH3 type without any beta-UH3 admixture was prepared by high-pressure hydrogenation of bcc U stabilized by Zr. Such material, characterized by a general formula (UH3)(1-x)Zr-x, is stable in air at ambient and elevated temperatures. Hrelease is observed in the range of 400-600 degrees C similar to beta-UH3. Its stability allowed us to measure the magnetic properties, specific heat, and electrical resistivity in a wide temperature range. Despite the rather different crystal structure and inter-U spacing, the electronic properties are almost identical to beta-UH3. Its ferromagnetic ground state with Curie temperature T-C approximate to 180K (weakly and nonmonotonously dependent on Zr concentration) and U moments of 1.0 mu B indicate why mixtures of alpha- and beta-UH3 exhibited only one transition. Magnetic ordering leads to a large spontaneous magnetostriction omega(s) = 3.2 x 10(-3), which can be explained by the increase of the spin moment between the paramagn
