Metamagnetism in the high-pressure tetragonal phase of UTe${}_2$

T. Thebault, D. Braithwaite, G. Lapertot +3

A structural orthorhombic-to-tetragonal phase transition was recently discovered in the heavy-fermion compound UTe${}_2$ at a pressure $p^{\ast }\simeq 3-8$~GPa [Honda \textit{et al.}, J. P…
