摘要：
Magnetic properties of R2Fe2Si2C (with R = Nd, Tb) have been studied by means of neutron diffraction. An antiferromagnetic behaviour have been evidenced below 15K for the Nd based compound and 45 K for the Tb based compound. The magnetic cell is twice the crystallographic one, with a propagation vector k = (0, 0, 1/2). The main original feature of both structures is the non-colinearity between both R and Fe sublattices, the magnetic moments being nearly perpendicular.
