Influence of external magnetic field on the electrical transport properties of the FeSe/STO.^{[ 8 ]} (a) A series of I – V curves taken under varied magnetic fields at 3 K. (b) Temperature dependence of measured 4PP resistance at various external magnetic field. (c) Magnetic-field dependence of measured 4PP resistance at various temperatures around T _c. (d) Relation between the critical values of magnetic field and temperature. Filled triangles and circles are experimental results deduced from panels (b) and (c), respectively. Error bars are defined by the difference of temperatures where the measured resistance reaches zero. The solid line is a fit to Eq. ( 7 ).
