Abstract: | Muon spin rotation data on a single crystalline gadolinium sample have been obtained as function of temperature and hydrostatic
external pressure up to 0.6 GPa.
In the ferromagnetic state the application of pressure has a strong influence on the whole spin‐turning‐process of the spontaneous
magnetization: The onset of the spin‐turning is shifted towards lower temperatures with a rate of approximately dTst/ dp\approx -50 K/GPa. Higher values of the turning angle up to \varthetaext=90\circ can be reached and stabilized over a wider temperature range. At low temperatures the magnetization turns back again.
In the paramagnetic regime the data show a similar behaviour as under ambient pressure: both the Knight‐shift and the muon
spin relaxation show deviations from their high temperature behaviour in the critical regime below (T-TC) < 10 K. So there is no indication of pressure induced effects in this temperature range.
