Properties of Exchange Coupled All-garnet Magneto-Optic Thin Film Multilayer Structures

The effects of exchange coupling on magnetic switching properties of all-garnet multilayer thin film structures are investigated. All-garnet structures are fabricated by sandwiching a magneto-soft material of composition type Bi(1.8)Lu(1.2)Fe(3.6)Al(1.4)O(12) or Bi(3)Fe(5)O(12):Dy(2)O(3) in between...

Sumario:The effects of exchange coupling on magnetic switching properties of all-garnet multilayer thin film structures are investigated. All-garnet structures are fabricated by sandwiching a magneto-soft material of composition type Bi(1.8)Lu(1.2)Fe(3.6)Al(1.4)O(12) or Bi(3)Fe(5)O(12):Dy(2)O(3) in between two magneto-hard garnet material layers of composition type Bi(2)Dy(1)Fe(4)Ga(1)O(12) or Bi(2)Dy(1)Fe(4)Ga(1)O(12):Bi(2)O(3). The fabricated RF magnetron sputtered exchange-coupled all-garnet multilayers demonstrate a very attractive combination of magnetic properties, and are of interest for emerging applications in optical sensors and isolators, ultrafast nanophotonics and magneto-plasmonics. An unconventional type of magnetic hysteresis behavior not observed previously in magnetic garnet thin films is reported and discussed.
