Abstract The influence of Mo additions on the unusual magnetoelastic properties and Invar-type behavior of a Cr{sub 0.997}Ru{sub 0.003} antiferromagnetic alloy was investigated. Measurements were done of the temperature dependence of the thermal-expansion coefficient and bulk modulus of (Cr{sub 1{minus}{ital x}}Mo{sub {ital x}}){sub 0.997}Ru{sub 0.003} alloys with 0{le}{ital x}{le}0.07. Well-defined magnetic anomalies were observed at the N{acute e}el temperature implying large magnetic contributions to the thermal expansion and the bulk modulus, making these alloys suitable to be analyzed and parameterized in terms of existing theories. The addition of Mo to Cr{sub 0.997}Ru{sub 0.003} completely suppresses the presence of the commensurate spin density wave phase for {ital x}{ge}0.015 and does not improve the Invar-type behavior to a desired level that may be useful for practical applications. {copyright} {ital 1996 American Institute of Physics.} {copyright} {ital 1996 American Institute of Physics.}
