Low-temperature phase of yttrium iron garnet (YIG) and its first-order magnetoelectric effect

Low-temperature phase of yttrium iron garnet (YIG) and its first-order magnetoelectric effect

A structural change in YIG is revealed by the observation of a first-order magnetoelectric effect at 77 K. The signal disappears at around 130 K. This indicates that a phase transition takes place at this temperature. Detailed field cooling experiments lead to the conclusion that the symmetry of YIG...

Zusammenfassung:A structural change in YIG is revealed by the observation of a first-order magnetoelectric effect at 77 K. The signal disappears at around 130 K. This indicates that a phase transition takes place at this temperature. Detailed field cooling experiments lead to the conclusion that the symmetry of YIG below 130 K is triclinic.
