Magnetic properties of C14 laves phase Ti(Fe1−xVx)2 and Ti(Fe1−xCrx)2 with x<0.5

Abstract The C14 Laves phase TiFe 2 is an antiferromagnet with a Neel temperature of about 285 K. The magnetic properties and the phase diagrams of V and Cr substituted systems for Fe have been investigated using magnetization and V-NMR measurements. The antiferromagnetism in TiFe 2 is suppressed by both the substitutions. In the V substituted case the magnetic state changes to ferromagnetism (0.15 x x =0.1). In the Cr case the antiferromagnetism is kept till around x =0.3, while spontaneous magnetization appears in 0.075 x
