Hyperfine Magnetic Fields at exp 111 Cd in Heusler Alloys

摘要

The magnitudes and signs of the hyperfine magnetic field on exp 111 Cd nuclei at Z sites in the ordered ferromagnetic Heusler alloys X sub 2 MnZ and XMnZ (where X is Cu, Ni, Pd while Z is In, Sn and Sb) have been investigated at liquid nitrogen and room temperatures using TDPAC method. Their signs have been found to be negative. The results have been compared with the predictions of Caroli-Blandin and Campbell-Blandin models and RKKY theory. (Atomindex citation 11:547361)
