  • Magnetooptic element exploiting spin chirality
    Patent number: 6985276
    Abstract: A magnetooptic element whose size is essentially that of a lattice, namely several angstroms in size of magnetic material and which at the same time has its exhibiting magnetooptic effect detectable is provided along with a magnetooptic disk, a memory device and a magnetooptical picture or image display with a storage capacity of several terabits per square inch or more, each using such a magnetooptic element. The magnetooptic element utilizes a gigantic effective magnetic filed based on a spin chirality formed by geometrically configuring the spin orientation and crystallographic structure of a certain solid material.

  • Single crystal manufacturing method
    Patent number: 5785753
    Abstract: In a single-crystal manufacturing method, after a single crystal is grown, the crystal is separated from the molten melt and gradually cooled while suspended immediately above the surface of the melt. During this cooling, a measure, which produces solidification of the melt, is locally applied. As a result, the solidification of the melt is selectively forced so that at least the melt forms a crust and prevents the crystal, should it fall, from becoming immersed in molten melt. This measure also protects the crystal from any sudden release of heat such as tends to occur if the melt becomes supercooled prior to the onset of crystallization.
