Abstract

We have studied the pressure effect on magnetostriction, both in the $ab$ -plane and along the c-axis, of a (La,Pr) $_{1.2}$ Sr $_{1.8}$ Mn $_{2}$ O $_{7}$ bilayered manganite single crystal over the temperature region where the field-induced ferromagnetic metal (FMM) transition takes place. For comparison, we have also examined the pressure dependence of magnetization curves at the corresponding temperatures. The applied pressure reduces the critical field of the FMM transition and it enhances the remanent magnetostriction. An anomalous pressure effect on the remanent lattice relaxation is observed and is similar to the pressure effect on the remanent magnetization along the c-axis. These findings are understood from the view point that the double-exchange interaction driven FMM state is strengthened by application of pressure.
