Abstract
Small angle neutron scattering experiments have been carried out in the mixed state to determine the values and anisotropy of the penetration depth and coherence length in the superconductor β-PdBi2. The distortion of the vortex lattice observed on changing the magnetic field direction suggests that the a–c anisotropy of penetration depth in β-PdBi2 is small. With the magnetic field applied along the c-axis, we estimated the magnitudes of the penetration depth and coherence length by analyzing the magnetic field dependence of the neutron scattering intensity from the vortex lattice. The estimated superconductor parameters are consistent with the upper critical field obtained from the magnetization measurement.
