    Correlations between the magnetovolume effects and the type of magnetic ordering in the Lu2Fe17-based intermetallics are shown for the example of variation of the interatomic distances by means of substitution of Ce for Lu, hydrogenation and subsequent high-pressure investigation of both the initial (Lu0.8Ce0.2)2Fe17 and a hydride (Lu0.8Ce0.2)2Fe17H0.4 single-crystalline compounds. Hydrogenation is found to suppress totally the antiferromagnetic order of (Lu0.8Ce0.2)2Fe17 by favoring domination of the ferromagnetic interactions which increases the magnetic ordering temperature from 247 to 300 K. The application of pressure decreases the Curie temperature and induces the non-collinearity of the magnetic moments in (Lu0.8Ce0.2)2Fe17H0.4.
