A spin glass behavior is reported for the first time in metastable fcc FeRh. The spin glass is obtained in nanocrystalline state by ball-milling of an ordered bcc (B2) antiferromagnetic FeRh intermetallic compound, which is converted to a metastable disordered fcc spin glass structure. The process is similar to that reported for obtaining the newly discovered nanocrystalline GdAl2 spin glasses (Zhou G. F. and Bakker H., Phys. Rev. Lett., 73 (1994) 344). The fcc FeRh spin glass exhibits a freezing temperature K.
