【 摘 要 】

If a single spin possessing an easy-axis anisotropy is subjected to an external field perpendicular to the easy axis, the susceptibility exhibits a peculiar peak. We establish that the specific spectral properties of quantum fluctuations give rise to this peak. We predict that this effect takes place in real many-spin systems, such as Mn-12 clusters, and can be studied at finite temperatures in real experiments with attainable resolution. This offers an approach for studying quantum fluctuations in magnetic molecules, in addition to relaxation rate measurements.
