Pressure effect on spontaneous magnetization and first-order magnetizationprocess in the Er2Fe17 single crystal

A complex magnetic behavior of the Er2Fe17 compound can be characterized by the first-order magnetization process observed in the hard c magnetization direction. The magnetization and critical held H-CR of the first-order mag netization process in the Er2Fe17 single crystal have been measured under h ydrostatic pressure up to 10 kbar in the temperature range 5-300 K. A signi ficant decrease of the spontaneous magnetization with increasing pressure h as been observed. The value of H-CR increases under pressure at low tempera tures, but the pressure dependence of H-CR is more complex above 60 K. (C) 1999 Elsevier Science B.V. All rights reserved.
