In this work the results of investigation of microcavity one-dimensional magnetophotonic crystals GGG (111)/[TiO2/SiO2]5/M/[SiO2/TiO2]5 are presented, where M is single (Bi1,0Y0,5Gd1,5Fe4,2Al0,8O12) or double(Bi1,0Y0,5Gd1,5Fe4,2Al0,8O12/Bi2,8Y0,2Fe5O12 or Bi1,0Y0,5Gd1,5Fe4,2Al0,8O12/Bi1,5Gd1,5Fe4,5Al0,5O12) magnetoactive layers. Theoretical calculations and experiments showed that magnetooptical properties of microcavity one-dimensional magnetophotonic crystals can be improved using double layer iron garnet. In particular, the Faraday rotation can be significantly increased. It was determined, that depending on the crystal structure and magnetic layers composition magnetophotonic crystals with different types of magnetic anisotropy can be realized.
