Abstract: | Previous values of the pressure dependence of the magnetocrystalline anisotropy constant K1 of iron and nickel were revised. These values of K1?1 () depend on the magnetic field for iron, and do not for nickel. The value in iron extrapolated to infinitely strong magnetic field is ?7.8×10?6 bar?1 at room temperature and ?7.3×10?6 bar?1 at 77K, and in nickel at 15 KOe is ?7.5×10?6 bar?1 at room temperature and ?2.8×10?6 bar?1 at 77K. |
