Pressure effect on the three-dimensional charge-transfer ferromagnet [{Ru_2(m-FPhCO_2)_4}_2(BTDA-TCNQ)]

摘要

The magnetic properties of a three-dimensional infinite network compound, [{Ru_2(m-FPhCO_2)_4}_2(BTDA-TCNQ)] (m-FPhCO_2~- = m-fluorobenzoate; BTDA-TCNQ = bis(1,2,5-thiadiazolo)tetracyanoquinodimethane), were investigated under hydrostatic pressures up to 12.9 kbar. The applied pressure caused the intralattice exchange couplings to weaken, inducing a decrease in the magnetic phase transition temperature from 107 K at ambient pressure to 57 K at 12.9 kbar.
