Evolution of magnetic surfboards and spin glass behavior in (Fe 1-p Ga p ) 2 TiO 5
The unusual anisotropy of the spin glass transition in the pseudobrookite system Fe2TiO5 has been interpreted as arising from an induced, van der Waals-like, interaction among magnetic clusters. Here we present susceptibility (χ) and specific heat data (C) for Fe2TiO5 diluted with non-magnetic Ga, (...

| description | The unusual anisotropy of the spin glass transition in the pseudobrookite system Fe2TiO5 has been interpreted as arising from an induced, van der Waals-like, interaction among magnetic clusters. Here we present susceptibility (χ) and specific heat data (C) for Fe2TiO5 diluted with non-magnetic Ga, (Fe1-pGap)2TiO5, for disorder parameter p = 0, 0.11, and 0.42, and elastic neutron scattering data for p = 0.20. A uniform suppression of Tg is observed upon increasing p, along with a value of χ(Tg) that increases as Tg decreases, i.e. dχ(Tg)/dTg |
