High field magnetostriction and magnetization of uranium monoantimonide single crystals

ORAL

Abstract

Uranium monoantimonide (USb) crystallizes in the cubic NaCl-type crystal structure and is known to order antiferromagnetically with a triple-k magnetic structure, with a wave vector (1,0,0), below TN = 213 K. IIn addition, the extent of hybridization that occurs between the uranium's 5f electrons with conduction electrons and its role for magnetism is not fully understood. During the talk we will present results of our recent magnetization and magnetostriction measurements of high-quality single crystals of USb at pulsed magnetic fields up to 65 T. The magnetization measurements help us to reveal the energy scales that are important in USb. In addition, the magnetostriction measurements performed in wide temperature range provides better microscopic understanding of the spin-lattice coupling and its strength in this material. We will discuss implications of these results.
