Title: Angle Dependence Near the Critical Pressure of UTe2
Abstract: The candidate spin-triplet superconductor Uranium Ditelluride (UTe2) is of broad interest due to the possible topological nature of its ground state, which is proposed to be a rare spin-triplet superconductor. Multiple studies have been conducted on UTe2 to fully characterize the different phase transitions as functions of pressure, external magnetic field, and temperature [1]. Pressure is an intriguing tuning parameter as UTe2 lies near a quantum phase transition [1]. As hydrostatic pressure is applied to the system, the superconducting phases persist until the sample-dependent critical pressure, pc ~1.4-1.7 GPa, where both observed superconducting phases are suppressed [2,3]. To further explore these pressure-induced transitions, we performed detailed magnetoresistance measurements as a function of angle within the bc-plane, near the critical pressure. The results show a continuous evolution of the metamagnetic transitions as the field is rotated from the b- to the c-axis.
