Fig. 2

Nernst coefficient divided by temperature ν/T of Ba(Fe1−xRhx)2As2 as a function of T and x. All data measured along the ab-plane with a magnetic field of B = 14T 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. Rh doping level x at selected temperatures. d Colour coded phase diagram of the Nernst coefficient divided by temperature ν/T as a function of Rh doping level x and temperature T. Coloured arrows on the top mark show the nominal doping of the measured samples. TS, TN, and Tc data taken from ref. 20. Tnem data is obtained from elastoresistivity measurements on the same samples (compare “Methods” section).
