Abstract

The magnetic properties of RCo2B2 compounds which crystallize in the ThCr2Si2 structure with R = Nd, Gd, Tb have been investigated. The magnetic structure is ferromagnetic for NdCo2B2 and GdCo2B2, Tc equals 32 and 26 K respectively and antiferromagnetic for TbCo2B2 (TN = 19 K). Curie-Weiss behaviour is exhibited by all the compounds and the effective moments derived indicate that Co is diamagnetic. The difference in magnetic properties between RCo2B2 and other isomorphous RCo2X2 (X = Si, Ge) is discussed. Mössbauer studies of 155Gd in GdCo2B2 yielded the hyperfine interaction parameters and determined the direction of the magnetization to be in the basal plane. The electric quadropole interaction at 4.1 K is 580 MHz sec-1, this is the largest ever found in an intermetallic Gd containing compound.
