Hyperfine fields in acid ferric phosphate
- 15 Downloads
Mössbauer spectra of acid ferric phosphate show that the iron ion site has a nearly cubic symmetry. Below 30 K the substance is magnetically ordered and undergoes a phase transition at about 11 K. At 4.2 K ferrimagnetic order with canted spins was found, and a 13% contribution of antiferromagnetically ordered spins.
