Soft phonons and structural phase transition in superconducting Ba[subscript 0.59]K[subscript 0.41]BiO[subscript 3]

Soft phonons and structural phase transition in superconducting Ba[subscript 0.59]K[subscript 0.41]BiO[subscript 3]

We have observed a softening of phonons and a structural phase transition in a superconducting Ba[subscript 0.59]K[subscript 0.41]BiO[subscript 3] (T[subscript c] = 31 K) single crystal using elastic and inelastic neutron scattering measurements. The soft phonon occurs for the [1 1 1] transverse aco...
