Experimental measurement of the isolated magnetic susceptibility
The isolated susceptibility may be defined as a
(non-thermodynamic) average over the canonical ensemble, but while it has often
been discussed in the literature, it has not been clearly measured. Here, we
demonstrate an unambiguous measurement of at avoided
nuclear-electronic level crossings in a dilute spin ice system, containing
well-separated holmium ions. We show that quantifies the
superposition of quasi-classical spin states at these points, and is a direct
measure of state concurrence and populations.Comment: 9 pages, & figure
