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