RKKY interaction in metallic Gd in GPa pressure regions

Abstract The bulk magnetization of metallic Gd decreases with increasing pressure and disappears at 7 GPa . The Curie temperature reduces with pressure, and the ferromagnetic signals disappear above 7 GPa in the wider temperature region. These experimental results are discussed on the pressure induced frustration of the RKKY interactions among the 8 S 7/2 state of localized 4f electrons.
