Abstract
Magnetization of Ce0.75La0.25B6 has been measured under uniaxial pressure P similar or equal to 0.11 GPa applied parallel to the [1 1 0] direction in magnetic fields H up to 5T at temperatures between 0.4 and 3 K, with a spec ial interest in the strain effect on a new exotic ordered state (phase-IV). The magnetic susceptibility chi of phase-IV, which is isotropic at P = 0, becomes remarkably anisotropic under pressure as chi([1 1 0]) > chi([1 1 0] ), indicating that the magnetic state of phase-IV is very sensitive to the uniaxial strain. Effect of pressure is also evidenced in the magnetic respo nse in phase-m antiferromagnetic state especially at low-field region. (C) 2000 Elsevier Science B.V. All rights reserved.
