Labarta, AmílcarObradors, XavierTejada Palacios, JavierBerry, Frank J., 1947-Sarson, M.2012-10-092012-10-0919880021-8979https://hdl.handle.net/2445/32229We report here on the magnetic properties of compounds of composition Fe1−xCrxSbO4 and Fe1−xGaxSbO4. The introduction of paramagnetic Cr3+ and diamagnetic Ga3+ into the rutile‐related iron antimonate lattice does not destroy the antisite atomic ordering which exists in iron antimonate of composition FeSbO4. The initial slope of the Curie temperature dependence on x is similar in both series, indicating that Fe3+‐Cr3+ interactions are very small. The magnetic susceptibility measurements recorded from the compounds of composition Fe1−xCrxSbO4, x<0.4, and Fe0.9Ga0.1SbO4 show them to behave as spin glasses at low temperatures. The inhibition of compounds of the type Fe1−xCrxSbO4, x>0.4, and Fe1−xGaxSbO4, x>0.1 to undergo a spin‐glass transition above 4.2 K is associated with a dilution effect.3 p.application/pdfeng(c) American Institute of Physics , 1988Vidres de spinPropietats magnètiquesEfecte MössbauerMetall-òxid-semiconductorsSpin glassesMagnetic propertiesMössbauer effectMetal oxide semiconductorsinfo:eu-repo/semantics/article0437382012-10-09info:eu-repo/semantics/openAccess
