Description
Quantum spin ladders are fascinating systems with complex excitation spectra that depend on the relative strengths of the leg and rung exchange interactions. Here we report the magnetic properties of a new strong-leg spin ladder obtained by using magnetization, specific heat and neutron scattering measurements. In particular, we performed comprehensive inelastic neutron scattering experiments using both triple-axis and neutron time-of-flight techniques. Our results reveal a gapped excitation spectrum, consistent with the spin-ladder model. In addition, we will also show our magneto-thermodynamic experiments to demonstrate how the system transforms from a quantum paramagnet into a partially spin-polarized state.
