XRD pattern of a LiFeAs sample. The Inset is a photography of the LiFeAs single crystal with a well cleaved plane.
Temperature dependence of resistivity of LiFeAs single crystal for -plane and -axis. The left inset shows that the electrical anisotropy value of the sample is . The right inset shows the temperature dependence of the magnetic susceptibility of a LiFeAs single crystal measured in a 10 Oe.
(a) and (b) are resistivity measurement in magnetic fields of 0 T, 0.5 T, 1 T, 3 T, 5 T, 7 T, and 9 T for the -axis and -plane, respectively. Two insets display the temperature dependence of the upper critical field for and .
This diagram shows and for -direction simultaneously in LiFeAs.
