Existence of incommensurate spiral magnetic structure in Y2Fe17 under high pressure

Abstract Magnetization of Y 2 Fe 17 single crystals was measured under pressure up to 10 kbar and neutron diffraction studies of powdered samples of Y 2 Fe 17 were performed under pressure up to 30 kbar in the temperature range 4–300 K. The suppression of the collinear ferromagnetic structure and the presence of the non-collinear incommensurate magnetic structure were evidenced under pressure above 12 kbar in the whole temperature range.
