URhGe - Altermagnetic Ferromagnet

It is well known that the anomalous Hall effect in ferromagnetic and 
strongly paramagnetic metals in addition to electron skew scattering on 
impurities is determined by internal mechanism linked to the Berry 
curvature, a quantum-mechanical property of the electron states of a 
perfect crystal. Experimentally, however, it has been established that 
the Berry curvature does not play any role in the Hall resistance of the 
ferromagnet URhGe. URhGe is so called altermagnetic ferromagnet which 
crystal symmetry includes operation of time inversion only in 
combination with rotations and reflections. The explanation for strictly 
zero Berry curvature of electronic states in this material lies in the 
non-symmorphic symmetry of its crystal lattice.

Phase Diagram of UTe_2

The pressure-temperature phase diagram of superconducting UTe_2 with 
three lines of the second- order phase transitions cannot be explained 
in terms of successive transitions to superconducting states with a 
decrease in symmetry. The problem is solved using a two-band description 
of the superconducting state of UTe_2.
