Fig. 3

Nernst coefficient divided by temperature ν/T of LaFe1−xCoxAsO as a function of T and x. All data measured along the ab-plane with a magnetic field of B = 14 T applied parallel to the c-axis. a ν/T as a function of temperature (note the semi-logarithmic scale). b Zoom-in on the data shown in panel (a). Black arrows indicate structural phase transitions. c ν/T vs. Co doping level x at selected temperatures. d Colour-coded phase diagram of the Nernst coefficient divided by temperature ν/T as a function of Co doping level x and temperature T. Coloured arrows on the top mark show the nominal doping of the measured samples. TS, TN, Tc, and Tnem data taken from ref. 28.
