Abstract

The Pressure effect on the magnetic properties of the weak itinerant electron ferromagnet CrAlGe was investigated at pressures up to 1.0 GPa. The spontaneous magnetic moment ps and Curie temperature TC decreased with increasing applied pressure P. The pressure derivatives of ps and TC were dps=dP = -3.98 × 10-5 μB=MPa and dTC=dP = -6.58 × 10-3K=MPa, respectively. These obtained results are discussed on the basis of Takahashi's spin fluctuation theory for weak itinerant electron ferromagnets. The characteristic parameters T0 and TA increased with pressure.
