Research Abstract

The purpose of this project is to design a high pressure apparatus using a material which shows a change of the length on the phase transition induced by temperature or magnetic fields. In the present work, we used a shape memory alloy or giant magnetostrictive alloy as a device to generate high pressure. The results im the present work are summarized as follows,
1)We selected Ti-Ni shape memory alloy to generate a pressure, in which 3% lengh change is expected on the martensitic transformation. This means that 1 mm length change is expected when we use 30 mm Ti-Ni rod. The fundamental properties of this alloy are investigated.
2) By using this Ti-Ni one way shape memory alloy, it was revealed that we can reach about 10 GPa when we use Bridgman type apparatus having a face of 3 mm in diameter.
3) In the usual experiments, we repeat heating and cooling process to obtain the temperature dependence of the physical quantities such as volume or magnetic susceptibilities. For this reason, we used the two ways shape memory alloys in which the change in the length is smaller than that of one way alloys. It is found that we can get 5 GPa by using this alloy.
To conclude, we can reach 10 GPa or more using the Ti-Ni shape memory alloys, which gives a large progress in this research area. By applying this method to the diamond anvils, we will be able to get higher pressure than 10 GPa.
