Abstract
Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at Tf= 35 K and frequency-dependent susceptibility below Tf. The field-cooled and zero-field-cooled magnetization diverge below Tf, with hysteresis characteristic of a spin glass. A resistivity minimum just above Tf is explained in terms of coherent magnetic scattering. This behavior is common to spin glasses with short-range interactions among f-electron moments and indicates a similar spin configuration in these materials.
