Figure 3
The comparison of the possible effects of MW radiation absorption at the SmB6 surface and in the sample bulk. Open symbols correspond to raw integrated intensities normalized to the value at T = 1.8 K; symbols filled by colors denote the recalculated values assuming dominating surface contribution. Curves 1, 2 are the best fits obtained with the help of Equation (1); curves 3, 4 are the temperature dependences expected for Curie and Curie-Weiss spin susceptibilities assuming dominating surface contribution. Curves 3a and 4a are the same as curves 3 and 4 for the case when paramagnetic centers are uniformly distributed in the sample (see text for details).
