Structure and magnetism in compressed iron-cobalt alloys
""Combined Co K-edge XANES-XMCD and XRD measurements were used to shed light on the magnetic. and structural phase diagram of the Fe1−xCox alloy under HP in the Co-rich region (x ≥ 0.5). At 0.5 ≤ x ≤ 0.75, the alloy shows a pressure-induced structural\\\/magnetic phase transition from bcc-FM to hcpnon-. FM phase just like pure iron but at higher pressures. The x = 0.9 sample has an fcc structure in the. pressure range investigated but presents an FM to non-FM transition at P = 64 GPa, a significantly lower. pressure compared with pure Co (predicted ≈120 GPa), showing that Fe impurities strongly affect the HP.
