Anisotropic Spin-Glass Behavior inFe2TiO5

Abstract: It is shown that the insulating oxide Fe 2 TiO s exhibits anisotropic (uniaxial) spin-glass behavior below 55 K 0 Extensive experimental results supporting this conclusion, including principal magnetic susceptibility, neutron scattering, ultrasonic, specific heat, and oriented single-crystal Mossbauer measurements, are described.

“…The oxidized end‐member, Fe 2 3+ TiO 5 , received some interest in solid‐state physics because of its anisotropic spin glass transition below about 55 K [ Atzmony et al , 1979; Tholence et al , 1986; Srivastava and Hammann , 1987] and its magnetic semiconductor properties [ Pandey et al , 2006]. Srivastava et al [2003] reported that magnetic freezing along the c axis of the crystal is clearly visible in AC susceptibility of a powder sample as a broad maximum.…”

“…The thickness of the films was estimated by comparison of the observed images with calculated ones for different thicknesses. Atzmony et al (1979) reported the anisotropic spinglass behavior in FezTiOB and explained it to be ascribed to a random distribution of Fe + and Ti4+ ions in the orthorhombic unit cell. We newly determined the crystal structure of FezTi05 to be the ordered monoclinic structure (C2: a = 2.223, b = 0.373, c = 0.980 nm, and p = 116.2') by HRTEM and X-ray diffraction .…”

“…It is generally accepted that two conditions must be satisfied for a spin-glass transition to occur: interactions between spins must be disordered and these interactions must also be frustrated [2,3]. In canonical spin glasses-e.g., dilute magnetic alloys such as Cu 1−x Mn x [4] and site-disordered crystals such as Fe 2 TiO 5 [5]-the nature of structural disorder and its coupling to magnetism is well understood. However, spin-glass behaviour is also observed in well-ordered crystals where the geometry of the magnetic lattice alone can generate frustration (see, e.g., [6][7][8]).…”
