Figure 3. Temperature dependence of the spin injection into the surface states of SmB6.
(a) Magnetic field dependence of the voltage measured for the temperatures of 0.84, 1.66, 2.1, 2.3 and 10 K, respectively. The measurement is performed with a microwave power 100 mW and frequency of 10.1 GHz. (b) The resistance of the SmB6 as a function of the temperature from 10 to ∼0.8 K. (c) Temperature dependence of VSP.
