A Low Temperature Phase Transition in Yttrium Iron Garnet (YIG)

Magnetoelectric Effect in Magnetic Materials

“…Since Iα3d has inversion symmetry, no linear magnetoelectric effect but only that of quadratic in the electric field was expected and has been reported [71-73, etc.]. On single crystals prepared with floating zone method, however, first-order magnetoelectric effect has been observed recently, when the crystal is cooled in an external electric field from room temperature to 77 LC [74]. The sign of the signal is reversed by reversing the cooling electric field direction.…”

Electric field controlled Faraday rotation in an electro-optic/magneto-optic bilayer

“…14 In YIG the linear ME effect is observed in regions involving defects and at low temperatures, after cooling in simultaneously applied electric and magnetic fields. 15 In epitaxial YIG films, the ME constant can reach a maximum value ␣ ϳ 10 −2 at room temperature. 16 For our calculations, we assume the external electric field to be of magnitude E 0 =10 7 applying E 0 in the ͑101͒ direction leads to an enhancement of p F for both orientations of M for p-polarized incident light.…”

Light reflection from nonlinear optical dielectric film on a bigyrotropic magnetoelectric substrate at angles close to Brewster angles

“…19 for wavelength = 1.15 m. The amplitude of the electric field of the incident EMW is E ϳ 10 8 V / m, and the MES thickness is d NL = ,3 ,5. We note that the assumption made above that the diagonal components of the permittivity and permeability tensors are equal is applicable to a YIG film.…”
