Direct observation of symmetry-breaking in a 'ferroelectric' polar metal
Emma Berger, Sasawat Jamnuch, Can Uzundal +17
Ferroelectric materials contain a switchable spontaneous polarization that persists even in the absence of an external electric field. The coexistence of ferroelectricity and metal…
