Pressure dependence of the average atomic volume. The ruby fluorescence36 and neon equation of state (EOS)39 are used as a pressure gauge in the hydrostatic (a) and non-hydrostatic runs (b), respectively. The error bar of the measured average atomic volume is smaller than its symbol size. The hydrostatic volume data are fitted using the Vinet EOS in three different pressure ranges (solid lines). For comparison, the calculated EOSs of CoCrFeAl in ferromagnetic, paramagnetic, and non-magnetic states at 300 K are also presented (dash-dotted lines). The parameters of the EOS are listed in Table 1
