AbstractFluorides K0.5FeF3 with tetragonal tungsten bronze structure have been fabricated by solid state reaction at low sintering temperature in the range between 150 °C and 400 °C with the assistance of crystal water during the grinding and sintering processes. Unusual magnetic properties have been observed, including positive exchange bias field (H E) with negative vertical magnetization shift (Mshift), and smaller field cooling (FC) magnetization than the zero field cooling one below 53 K. The results are explained by a core-shell structure consisting of antiferromagnetic core and spin glass (SG) shell with antiferromagnetic interfacial coupling between the pinned interface spins and the SG shell spins. The sign of HE and Mshift can be changed by increasing the cooling field in the FC process, which is attributed to the competition between the antiferromagnetic interfacial coupling and the Zeeman energy of magnetization of the SG shell. © 2013 AIP Publishing LLC.
