Strong magnetic anisotropy in PrRuGaand PrCoAlsingle crystals.

Single crystals ofRuGaandCoAl(= La and Pr) were grown using a Ga/Al self-flux method. An orthorhombic CaCoAl-type structure with space group(No.55) of them was identified by x-ray diffraction.

Experimental evidence of anomalously large superconducting gap on topological surface state of β-BiPd film.

Connate topological superconductor (TSC) combines topological surface states with nodeless superconductivity in a single material, achieving effective p-wave pairing without interface complication. By combining angle-resolved photoemission spectroscopy and in-situ molecular beam epitaxy, we studied the momentum-resolved superconductivity in β-BiPd film. We found that the superconducting gap of topological surface state (Δ ∼ 3.
