| Research Abstract |
The high-field magnetization and magnetoresistance measurement of β-US_2 with semiconducting electrical resistivity in low temperatures were mainly carried out using the development of a new experimental equipment in high-magnetic field measurement. The electrical resistivity suddenly quenched at 4.2K in the high-magnetic field and reached to one hundred thousandth part of zero field value at 50T. The system is not semiconducting but metallic at 50T. The relationship between this great large negative magnetoresitance and the magnetization is found experimentally.
