Extended Data Fig. 10: Resistance of the platinum injector as a function of injection current and temperature.
From: Tunable long-distance spin transport in a crystalline antiferromagnetic iron oxide
The resistance of platinum is a reliable indicator of the local temperature of the area. An injection current of 600 μA (current density of 2.8 × 1011 A m−2) at 2 K corresponds to the same local temperature as the injector in a helium bath of 25 K with an injection current of 50 μA (current density of 2.3 × 1010 A m−2), signified by the identical resistance values at these two points and hence the same local temperature.
