High Field c-Axis Magnetotransport of Single Crystal Ytterbium, Nickel (2), Boron(2) Carbon

摘要

We have measured c-axis magnetotransport properties of the tetragonal YbNi2B2Ccompound down to 2 K and up to 18 T. Transverse and longitudinal magnetoresistance have been measured with current applied along the c-axis of tetragonal structure. A well-defined maximum in the magnetoresistance is observed at temperatures below 10 K at approximately 5 T. At higher temperatures the magnetoresistance is always negative and weakens as the temperature is increased.
