Unusual spectra with a significant decrease in circularly polarised emissions (Stokes parameter V ) in the middle part of the microwave range (6 - 12 GHz), sometimes with a change of the polarization sign, were revealed by observations with the radio telescope RATAN-600 in the microwave range 2 - 16 GHz. Such features can be explained by the presence of a hot region in the solar corona. The magnetic field strength of the hot region and the product of the relative gradient of the magnetic field on its thickness are defined.
