beta-NMR Investigation of the Depth-Dependent Magnetic Properties of an Antiferromagnetic Surface

By measuring the prototypical antiferromagnet alpha-Fe2O3, we show that it is possible to determine the static spin orientation and dynamic spin correlations within nanometers from an antiferromagnetic surface using the nuclear spin polarization of implanted Li-8(+) ions detected with beta-NMR. Remarkably, the first-order Morin spin reorientation in single crystal alpha-Fe2O3 occurs at the same temperature at all depths between 1 and 100 nm from the (110) surface; however, the implanted nuclear spin experiences an increased 1/T-1 relaxation rate at shallow depths revealing soft-surface...
