Magnetic torque of USb single crystals

ORAL

Abstract

Over 40 years, uranium monoantimonide (USb) has been investigated by a variety of experimental and theoretical methods. This compound crystallizes in the cubic NaCl-type of crystal structure and is known to order antiferromagnetically with a non-collinear triple-k magnetic structure below T_N∼214 K. This high-symmetry complex magnetic structure consists of three equivalent <0 0 1>-type of wave vectors, with spins that point along <1 1 1> direction. During the talk we will present results of our recent magnetic torque measurements performed on high-quality single crystals of USb at temperatures below and above T_N. The measurements have been carried out in both DC and pulsed magnetic fields up to 60 T. The results obtained are crucial in understanding of magnetic interactions, anisotropy, and their coupling to the lattice in this material. We will discuss implications of these results.
