摘要： A thermally-stable ferroelectric memory is provided. The ferroelectric memory includes a lower electrode and a ferroelectric layer formed on the top surface of the lower electrode such that a domain having a dielectric polarization is set as a bit. The thickness of the ferroelectric layer is not greater than the size of the bit. Accordingly, a non-volatile ferroelectric memory which is thermally stable is provided, thereby realizing a reliable memory which can store information at high speed and high density and has improved memory retention.

摘要： A Lorentz force microscope and a method of measuring magnetic domains using Lorentz force are provided. The Lorentz force microscope includes: a conductive probe which is actuated by Lorentz force occurring due to the interaction between a magnetic field of the magnetic medium and current applied into the magnetic field; a bottom electrode which is prepared on one side of the magnetic medium, for charging the magnetic field with electricity; a scanner for supporting the magnetic medium on which the bottom electrode is prepared and actuating the magnetic medium when the conductive probe opposite to a record of the magnetic medium scans the record of the magnetic medium; and an information detector for controlling the scanner and detecting information on magnetization of the magnetic medium from motion components of the conductive probe. Directions of Lorentz force which is applied to the conductive probe are sensed in a state that the conductive probe contacts or does not contact the magnetic medium to detect magnetization directions of the magnetic domains. Thus, a magnetic domain distribution map having improved resolution can be obtained.

摘要： A cathode ray tube for multimedia includes a shadow mask having a plurality of beam-guide apertures. Each of the beam-guide apertures has a stripe shape and the ratio of a horizontal length of an effective screen to a horizontal pitch of the beam-guide apertures in the center of the shadow mask is in the range of 1:8.81×10−4 to 1:1.23×10−3. The ratio of the horizontal pitch of the beam-guide apertures in the center of the shadow mask to the thickness of the shadow mask is in the range of 1:0.25 to 1:0.56.
