Abstract (in Japanese) (See Japanese page) 
(in English) In order to realize high density and high speed ferroelectric recording, we made and measured a series of thin film with changing the PbO sputtering power and thickness to look for the best recording film and minimum record point.
With the changing of PbO sputtering power as an experimental parameter, the ferroelectricity of film changes drastically. This can be considered to be inadequate and excessive Pb supply in the process. The 35, 40 and 45W PbO sputtering power films showed excellent crystal quality, which is examined by XRD and also showed good ferroelectricity from the results of P-E hysteresis curve and dot forming test. Especially the 40W PbO sputtering power film showed best quality.
As the film thickness decreased, coercive field increased. In spite of this, we succeeded to obtain high quality film with the thickness of 60nm, in which 35nm dot was formed in diameter with high switching speed.
