Nature of spiral state and absence of electric polarisation in Sr-doped YBaCuFeO5 revealed by first-principle study
Abstract Experimental results on YBaCuFeO5, in its incommensurate magnetic phase, appear to disagree on its ferroelectric response. Ambiguity exists on the nature of the spiral magnetic state too. Using first-principles density functional theory (DFT) calculations for the parent compound within LSDA...
