Magnetization of single crystalline strontium ruthenate under uniaxial-pressure

Abstract In order to extract the intrinsic magnetic correlations in Sr 2 RuO 4 , we have performed magnetization measurements under uniaxial pressures ( p 2 plane. The single crystalline sample grown by a floating-zone method has been used. The results indicate that the magnetization remains paramagnetic up to the maximum pressure without showing any sign of substantial magnetic transitions. Larger pressure is probably necessary to induce ferromagnetic or antiferromagnetic ordering associated with the nature of superconductivity.
