Abstract
We report a clear anomaly in the rf response of a tunnel-diode resonator measured in borocarbide crystals in dc fields along the axis. We associate the anomaly in the dynamic magnetic susceptibility, , with a structural transition in the vortex lattice. is sensitive to the Campbell penetration depth of the rf perturbation into the mixed state. depends on the vortex lattice elastic moduli, which in turn depend on the vortex lattice structure. The high-field transition line is clearly mapped and shown to behave in agreement with theory.
