    Abstract
  • Four electrodes method and the magnetic sputter film deposition technique combined with photolithographic shaping method are used to measure the electrical resistance of iron up to 25 GPa. Furthermore, in-situ high pressure X-ray diffraction experiment was performed for measuring the lattice parameters of iron under high pressures up to 25 GPa. The experimental results indicated that the process of bcc-hcp phase transition of iron initiated at 13.7 GPa and finished at 18.1 GPa. The pressure dependence of electrical conductivity of iron was finally deduced from the resistance data and the X-ray diffraction results.
