Anisotropies and Homogeneities of Superconducting Properties in Iron-Platinum-Arsenide Ca10(Pt3As8)(Fe1.79Pt0.21As2)5

We report a study on the anisotropy of superconducting properties in single crystalline Ca10(Pt4-{\delta}As8)(Fe1.79Pt0.21As2)5 with Tc ~13.6 K. Under a field of 5 Oe, the sample reaches fully-diamagnetic state at ~10 K for H//c, and ~8 K for H//ab, indicating the presence of slight inhomogeneities. The magnetization measurements reveal fish-tail effect in the hysteresis loop for both H//c and H//ab. Averaged critical current densities at low magnetic fields along the c-axis and ab-plane Jc(H//c) and Jc(H//ab) at 5 K are estimated to be 0.910^5 and 0.710^5 A/cm2, respectively. Resistive transitions under magnetic field show broadening, which is consistent with a relatively large anisotropy of upper critical field. Magneto-optical images reveal homogenous current flow within the ab-plane.
