Cryogenic magnetocaloric effect in the Fe17 molecular nanomagnet.
Number: pap. ID: 233
Author(s) : GASS I. A., BRECHIN E. K., EVANGELISTI M.
Summary
We study the magnetic and magnetothermal properties of a magnetically isotropic high-spin molecular nanomagnet containing 17 Fe3+ ions per molecule linked via oxide and hydroxide ions. Low-temperature magnetization and heat capacity experiments reveal that each molecular unit carries a net spin ground state as large as S = 35/2 and a magnetic anisotropy as small as D = -0.023 K. These characteristics result in a large magnetocaloric effect in the liquid-helium temperature range, e.g. -delta Sm up to 8.9 J kg-1 K-1 for a 7 T applied-field change, suggesting that the Fe17 molecular nanomagnet can potentially be employed as a lowtemperature magnetic refrigerant.
