Abstract
A device that includes a near field transducer (NFT); at least one cladding layer adjacent the NFT; and a discontinuous metal layer positioned between the NFT and the at least one cladding layer.
Claims20
A device comprising:
- a near field transducer (NFT);
- at least one cladding layer adjacent the NFT, the cladding layer comprising
- SiO2;
- Al2O3;
- MgO;
- TaSiOx;
- MgF2;
- SiON;
- Y2O3;
- binary oxides of a metal oxide (MeOx) and AlOx, where Me is Ti, Hf, Zr, Nb, and Ta and 0<x<3.0;
- binary oxides of Y2O3 and AlOx;
- binary oxides of SiO2 and Al2O3;
- binary oxides of Y2O3 and SiO2;
- binary oxides of MeOx and SiO2 where Me is Ti, Hf, Zr, Nb, and Ta and 0<x<3.0;
- SiOxNy, where 0<x<2.0 and 0<y<1.33;
- or
- combinations thereof;
- and
- a discontinuous metal layer positioned between the NFT and the at least one cladding layer.
