Rongwei Hu, J. B. Warren, C. Petrovic

摘要:

本文报道了Fe_{1+y} Te_{1-x} S_{x}的单晶生长和超导性质的研究。在所有铁基超导体中,我们证明了最小的上临界场各向异性,γ = H_{c2} ^{//c}/ H_{c2} ^{//a},对于Fe_{1.09} Te_{0.89} S_{0.11},在T=0.65 T_{C}时γ值达到1.05,同时仍然保持大的上临界场值。

英文摘要:

We report single crystal growth and a study of superconducting properties in Fe_{1+y}Te_{1-x}S_{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_{1.09}Te_{0.89}S_{0.11}, while still maintaining large values of upper critical field.
