Abstract

It is shown that the insulating oxide ${Fe}_{2}$ Ti $O_{5}$ exhibits anisotropic (uniaxial) spin-glass behavior below 55 K. Extensive experimental results supporting this conclusion, including principal magnetic susceptibility, neutron scattering, ultrasonic, specific heat, and oriented single-crystal Mössbauer measurements, are described.
