Abstract Scope At room temperature, uranium metal is in its alpha form. It is hard and brittle unless alloyed with zirconium or other transition metals to form the room temperature stabilized delta-phase (UZr2). The delta-phase is known to have hexagonal crystal structure but the physical properties (especially at low temperatures) are largely unknown. In general, it is important to understand the physical properties of U-Zr alloys due to their technological importance as a nuclear fuel. Three UZr2+x (x = 0, 0.3, and 0.6) compounds have been synthesized and characterized by X-ray diffraction. Here, we present the first-time results of the magnetic, transport, and thermodynamic measurements of the uranium delta-phase at low temperatures and under high magnetic fields. We will discuss implications of these results, especially in the context of 5f-electron localization/delocalization in this material.
