The effect of the incommensurate-commensurate SDW transition on the magnetoelasticity of dilute Cr-Ru alloys
Measurements of the temperature dependence of the elastic moduli and the thermal expansion of two Cr-Ru alloys containing 0.3 and 0.5 at.% Ru are reported. In addition to anomalies at the transition from the incommensurate (I) to the commensurate (C) phase and from C to the paramagnetic phase in both the thermal expansion coefficient and the bulk modulus a new anomaly in the shear modulus has been observed at TIC. Existing itinerant electron theories have been applied to analyse the data. In particular (1/TN)d2TN/d gamma 2, where gamma is the shear strain and TN the Neel temperature has been found to be (13+or-3) and (11+or-3) for the 0.3 and 0.5 at.% Ru alloys respectively.
