Studies of the Vortex Lattice in Sr 2RuO4 with H || a

DOI

Sr2RuO4 is an unconventional superconductor. While this is generally believed to have triplet pairing, this conclusion have recently been questioned [K. Machida and M. Ichioka, Phys. Rev. B 77, 184515 (2008)]. In stead is it proposed that many of the observations which were used to argue in favor of triplet pairing (e.g. specific heat) can also be explained as being due to Pauli paramagnetic effects (PPE).Initial studies of Sr214 with the field close to the a-axis showed a signal due to the transverse field modulation giving rise to spin flip scattering which is increased dramatically above the non-spin flip scattering. Our results showed a large anisotropy with a possible field dependence. Furthermore, the scattered intensity show a non-monotonic behavior, with a maximum occurring at an angle relative to the basal plane which varies with the applied field.Here we propose to extend our measurements to higher fields which we not available during earlier experiment performed at D22.
