摘要： Proposed is a grain boundary-free crystalline body of a perovskite structure having a chemical composition of the formula Pr.sub.1-x M.sub.x MnO.sub.3, in which M is calcium or strontium and the subscript x is a number of 0.3 to 0.5, which exhibits a magnetoresistance behavior with a phase transition between an insulator phase and a ferromagnetic metallic phase accompanied by the phenomenon of hysteresis. This grain boundary-free crystalline body can be obtained by subjecting a sintered body of a powder blend consisting of the oxides of praseodymium, manganese and calcium or strontium to a crystal growing treatment by the floating zone-melting method in an atmosphere of oxygen.

摘要： Disclosed is a high-pressure generation apparatus, which comprises a pair of columnar-shaped anvils disposed in opposed relation to one another to define a pressure-generating space therebetween. The anvils are adapted to be applied with a load therebetween to generate a high pressure in the pressure-generating space. Each of the anvils has a top portion formed in an approximately circular truncated cone shape, and the top portion has a central region formed with a depression having a side surface which extends obliquely outward. The high-pressure generation apparatus also includes a cylindrical capsule disposed in a central area of the pressure-generating space, and a laminated member formed by alternately laminating a doughnut-shaped metallic thin plate and a doughnut-shaped insulating member along the outer periphery of the capsule. The improved shape of the depression makes it possible to significantly reduce damages of the components. In addition, the laminated member formed of the metallic thin plate and the insulating member originally used for sealing the pressure-generating space makes it possible to generate a higher pressure.

摘要： A variable resistance element comprises a variable resistor of strongly-correlated material sandwiched between two metal electrodes, and the electric resistance between the metal electrodes varies when a voltage pulse is applied between the metal electrodes. Such a switching operation as the ratio of electric resistance between low and high resistance states is high can be attained by designing the metal electrodes and variable resistor appropriately based on a definite switching operation principle. Material and composition of the first electrode and variable resistor are set such that metal insulator transition takes place on the interface of the first electrode in any one of two metal electrodes and the variable resistor by applying a voltage pulse. Two-phase coexisting phase of metal and insulator phases can be formed in the vicinity of the interface between the variable resistor and first electrode by the work function difference between the first electrode and variable resistor.
