| Abstract | Magnetic properties of Gd-2(fum)(3)(H2O)(4)center dot 3H(2)O were investigated by static and alternating susceptibility, specific heat and adiabatic magnetization. The material is characterized by weak antiferromagnetic interactions, arising predominantly from dipolar couplings that leads to magnetic ordering at T-N = 0.19 K. A pronounced change in the magnetic entropy was found near the critical temperature. The magnetocaloric behavior estimated from specific heat data is confirmed by adiabatic magnetization above 0.2 K. In addition, adiabatic magnetization and demagnetization near the critical temperature revealed only a small hysteresis. Finally, the magnetothermal response and resulting refrigeration capacity of Gd-2(fum)(3)(H2O)(4)center dot 3H(2)O is compared with other magnetic refrigerants proposed for low-temperature applications.
