Magnetic Constitution and Elastic Properties of the Hydrogenated Permalloy Under Pressures of the Earth’s Core. Interpretation of Experiment
Electronic structure and magnetic properties of the crystallographically ordered hydrogenized permalloy at extreme pressures of the Earth’s core are studied by ab initio spin-polarized calculations. Both in high and low hydrogen-concentration limits, these ordered solid solutions keep pronounced fer...

| description | Electronic structure and magnetic properties of the crystallographically ordered hydrogenized permalloy at extreme pressures of the Earth’s core are studied by ab initio spin-polarized calculations. Both in high and low hydrogen-concentration limits, these ordered solid solutions keep pronounced ferromagnetic alignment up to sesquifold volume compression, at least, at zero temperature, although, with increasing H concentration, the magnetization decreases in a whole pressure range. The elastic characteristics of these intermetallics are studied with the goal to compare the values of calculated velocities of sound waves with the values of observed velocities of seismic waves propagating through the inner core. An attempt is made to estimate the melting temperatures of such compounds at the extreme pressures. |
