Effect of pressure on the metamagnetic transition of DyB6 single crystal

Abstract The effects of pressure on the magnetization ( M ) and the magnetostriction (MS) for DyB 6 single crystal have been measured at 4.2 K. It is found that the M loops are insensitive to pressure, whereas the large MS with magnitude of 0.5% at 5 T at ambient pressure is rapidly suppressed by applying pressure. The metamagnetic transition field H M in the M curve increases slightly by applying pressure with the rate of increase, ∂ ln H M /∂ P , of 0.03 GPa −1 , which is almost the same value as that for T N , 0.04 GPa −1 .
