Emergent Polar Metal Phase in a Van der Waals Mott Magnet
Shiyu Deng, Matthew J. Coak, Charles R. S. Haines +16
We report the emergence of a two-dimensional (2D) polar metal phase in van der Waals compound FePSe under moderate pressures. This layered material is a Mott insulator with ant…

Dome-like pressure-temperature phase diagram of the cooperative Jahn--Teller distortion in NaNiO
Liam A. V. Nagle-Cocco, James M. A. Steele, Shiyu Deng +6
NaNiO is a Ni-containing layered material consisting of alternating triangular networks of Ni and Na cations, separated by octahedrally-coordinated O anions. At ambient…

Magnetoelastic coupling in the stretched diamond lattice of TbTaO
Xiaotian Zhang, Nicola Kelly, Denis Sheptyakov +4
The magnetic structure of diamond-like lattice has been studied extensively in terms of the magnetic frustration. Here we report the distortion of stretched diamond lattice of Tb$^…
