Abstract
A ferroelectric recording medium includes an electrode layer, a ferroelectric recording layer, and a protection layer formed in this order on a substrate, wherein the ferroelectric recording layer includes a ferroelectric layer, and a lattice constant of a material constituting the ferroelectric layer and a lattice constant of a material constituting the electrode layer or the substrate are lattice-matched within a range of ±10%.
Claims9
A ferroelectric recording medium including an electrode layer, a ferroelectric recording layer, and a protection layer formed in this order on a substrate,
- wherein the ferroelectric recording layer includes a ferroelectric layer and a paraelectric layer, the paraelectric layer being disposed between the ferroelectric layer and the electrode layer,
- the paraelectric layer includes one or more paraelectrics selected from the group comprising oxide, nitride, carbide, boride, and silicide,
- a lattice constant of a material constituting the ferroelectric layer and a lattice constant of a material constituting the electrode layer or the substrate are lattice-matched within a range of ±10%, and
- a lattice constant of a paraelectric constituting the paraelectric layer and a lattice constant of a ferroelectric constituting the ferroelectric layer are lattice-matched within a range of ±10%.
