Field-induced slow magnetic relaxation and magnetocaloric effects in an oxalato-bridged gadolinium()-based 2D MOF

The coexistence of field-induced slow magnetic relaxation and moderately large magnetocaloric efficiency in the supra-Kelvin temperature region occurs in the 2D compound [Gd III 2 (ox) 3 (H 2 O) 6 ] n ·4 n H 2 O ( 1 ), a feature that can be exploited in the proof-of-concept design of a new class of slow-relaxing magnetic materials for cryogenic magnetic refrigeration. Field-induced SIM behaviour and remarkable cryomagnetic properties coexist in a well-known oxalato-bridged gadolinium( iii )-based 2D MOF.
