Effect of pressure on the magnetostriction and the magnetization of Eu(0.58)Sr(0.42)MnO3

Magnetostriction and magnetization of Eu0.58Sr0.42MnO3 were measured under hydrostatic pressures up to 2.0 GPa in order to investigate the effect of p ressure on the metal-insulator (M-I) transition, recently investigated by r esistivity measurements. At ambient pressure, around 2 T and 6 K, where the field-induced M-I transition was previously reported, the observed magneto striction was estimated to be 0.04%, With increasing pressure, the saturati on magnetization increased at a field of 0.5 T, whereas it decreased at fie lds of 1.5 and 5.0T.
