Abstract: New measurements of the magnetic field of chemically peculiar stars HD 178892 and HD 201174 are presented in the article. It has been confirmed that HD 178892 has an extremely strong magnetic field compared to other cool CP stars. First measurements of the magnetic field of the star HD 201174 have been carried out. A strong cross-over effect indicating the complex structure of the stellar magnetic field has been discovered in the Zeeman spectra of HD 201174. The analysis of chemical composition of the atmosphere of HD 178892 in phases when the magnetic field has its minimum and maximum has not revealed any variations in the abundance of the main chemical elements.

Keywords: magnetic field, CP stars, atmosphere, chemical composition.
