Destruction of long-range magnetic order in an external magnetic field and the associated spin dynamics in Cu2GaBO5 and Cu2AlBO5 ludwigites

A. A. Kulbakov, R. Sarkar, O. Janson +12

The quantum spin systems Cu${}_2$M'BO${}_5$ (M' = Al, Ga) with the ludwigite crystal structure consist of a structurally ordered Cu${}^{2+}$ sublattice in the form of three-leg ladders,…
