Abstract
Abstract—Temperature dependences of the third-harmonic power for the (Na0.3K0.7)xFe2 – ySe2 sodium–potassium ferroselenide single crystals have been investigated by nonlinear near-field microwave microscopy. The temperature dependence of magnetic susceptibility at a frequency of 100 kHz for this compound has been measured. The experimental results suggest a double-gap structure of the (Na0.3K0.7)xFe2 – ySe2 superconductor.
