Features of the hyperfine field at the nucleus of the ion 57Fe2+ in antiferromagnetic CoCO3
Ivanov M. A., Loktev V. M., Pogorelov Yu. G.
It is shown that the hyperfine field Hhf at the nucleus of the ion 57Fe2+ in C0CO3 is anomalously small but grows rapidly in an external field which lifts the reduction of the electron spin. A study is made of the temperature dependence οϊΗΜ and of the NMR gain.
