Abstract

We have investigated the magnetic properties of R₂Fe ₃O₇ (R=Yb and Lu), which belongs to the homologous family of electronic ferroelectric RFe₂O₄. Magnetization measurements show ferrimagnetic ordering at the Néel temperature (T _N) of ∼270 K, which is slightly higher than that of RFe ₂O₄ (T_N∼230-250 K). Observation of spin glass and exchange bias shows a coexistence of ferromagnetic and antiferromagnetic interactions, similarly to RFe₂O₄. This situation gives rise to a complex magnetic change and a broad peak of magnetic entropy change. Some characteristics, such as refrigeration temperatures higher than in RFe₂O₄, seem to offer a possibility of this system to applications.
