Abstract

We report single crystal growth and a study of superconducting properties in Fe_1+yTe_1-xS_x. We demonstrate the smallest upper critical field anisotropy, gamma=H_c2^//c/H_c2^//a, among all iron based superconductors, the value of gamma reaches 1.05 at T=0.65T_C for Fe_1.09Te_0.89S_0.11, while still maintaining large values of upper critical field.
