Resumo

Тhe article presents the results of investigation of thin films of rare-earth helimagnetics (REM) Dy and Ho by polarized neutron reflectometry. It was shown that the growth of rare-earth structures on sapphire substrates with a buffer layer of Nb by magnetron sputtering Al2O3||[110]Nb|| results in complete relaxation of the NB crystal lattices and the rare-earth film. It was found that a number of magnetic phase transitions characteristic of bulk Dy and Ho are not observed in thin films (200 nm) or are observed in a modified form. Also, from the data of polarized neutron reflectometry and measurements of the temperature dependence of the magnetization in the sample plane, differences in the Neel and Curie temperatures for thin REM films compared to bulk REM were determined.
