Application of the finite-temperature Lanczos method for the evaluation of magnetocaloric properties of large magnetic molecules
Full text linkWe discuss the magnetocaloric properties of gadolinium containing magnetic
molecules which potentially could be used for sub-Kelvin cooling. We show that
a degeneracy of a singlet ground state could be advantageous in order to
support adiabatic processes to low temperatures and simultaneously minimize
disturbing dipolar interactions. Since the Hilbert spaces of such spin systems
assume very large dimensions we evaluate the necessary thermodynamic
observables by means of the Finite-Temperature Lanczos Method.Comment: 7 pages, 10 figures, invited for the special issue of EPJB on "New

No full textThe 1:2:1 reaction of CdCl2·2.5H2O with 3,4-dihydroxybenzoic acid (3,4-H3dhb) and KOH in PrnOH-H2O gave the unique, seven-coordinate cadmium(II) complex [Cd(3,4-H2dhb)2(H2O) 3]·HCl·(3,4-H3dhb)·2.5H2O as one of the products. Crystal structure and 13Cd NMR studies showed that 3,4-H2dhb- behaves as a bidentate chelate with ligated atoms being the carboxylate oxygens, but that seven-coordination is not retained in aqueous solution.
