The Musfeldt Group recently published their work “Spin-Lattice Coupling Across the Magnetic Quantum-Phase Transition in Copper-Containing Coordination Polymers” in Inorganic Chemistry.
The group employs a series of copper-containing coordination polymers as a platform for exploring spin−lattice coupling across the magnetic quantum-phase transition. This interaction, which they quantify for the out-of-plane pyrazine bending mode as a function of the magnetic and structural dimensionality, reaches a maximum in ladderlike [Cu(pyz)1.5(4-HOpy)2](ClO4)2 because of the intermediate dimensionality.
They also sought to reveal spin−phonon coupling under compression but instead discovered a pressure-induced transition in the ladder to a state that is likely ferroelectric.
