Magnetic properties of iron oxalatophosphates with layer and framework structures
Abstract
The magnetic properties of two iron(III) oxalatophosphates, Cs2Fe(C2O4)0.5(HPO4)2 and CsFe(C2O4)0.5(H2PO4)(HPO4), were studied. The zero-field-cooled and field-cooled magnetizations versus temperature curves showed Curie-Weiss behavior from room temperature down to about 70K. Antiferromagnetic ordering and frustration behavior were observed in distinct temperature ranges at lower temperature. The frustration behavior can be attributed to the Dzyaloshinsky-Moriya interaction of the dimerlike magnetic structure, which causes spin canting states.
