摘要

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