Drastic reduction of the R-Fe exchange in interstitially modified (Nd,Ho)2Fe14B compounds probed by megagauss magnetic fields
Original language description
In this paper, the full magnetization process demonstrated by the series of ferrimagnetic intermetallic compounds (Nd,Ho)2Fe14B and Ho2Fe14B and their hydrides with the maximum possible hydrogen content (for the given crystal structure type) is studied theoretically and experimentally using megagauss magnetic fields. We observe field-induced phase transitions from the initial ferrimagnetic to the forced-ferromagnetic state in magnetic fields up to 130 T and describe the magnetization process analytically. We find a drastic decrease of the critical transition fields in the hydrogenated compounds. This is due to extremely strong, nearly twofold reduction of the R-Fe intersublattice exchange interaction because of the combined substitution and hydrogenation effects. A comparative analysis of the magnetization behavior for the system Ho2Fe17-H is also performed.
