Deskripsi
Materials with ordered magnetic spiral phases can exhibit ferroelectricity and magnetoelectric effects, but applications are restricted by low magnetic-order temperatures. Here, the authors stabilize the magnetic spiral phase of YBaCuFeO5at room temperature by controlling the iron–copper chemical disorder.
