Magneto-optical element and optical magnetic field sensor using the same |
| 摘要 |
A magneto-optical element comprises a film of a Bi-substituted rare earth iron garnet selected from garnets of the following chemical formulas(BixGdyRzY3-x-y-z)(Fe5-wGaw)O12wherein R represents at least one element selected from the group consisting of rare earth elements other than Gd, and x, y, z and w are such that 1.00</=x</=1.30, 0.42</=y</=0.60, 0.01</=z</=0.05 and 0.40</=w</=0.62, and(Bix'Gdy'Rz'Y3-x'-y'-z')Fe5O12wherein R is as defined above, and x', y' and z' are such that 1.10</=x'</=1.30, 1.00</=y'</=1.80, 0</=z'</=0.06. An optical magnetic field sensor capable of detecting zeroth to higher order beams of diffracted light is also described.
