Effect of pressure on the metamagnetic transition of DyB6 single crystal

The effects of pressure on the magnetization (M) and the magnetostriction (MS) for DyB6 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 5T 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, partial derivative In H-M/partial derivative P, of 0.03 GPa(-1), which is almost the same value as that for T-N, 0.04 GPa(-1).
