Magnetic form factor of molecular oxygen

Abstract

Using neutron diffraction the magnetic form factor f of oxygen is investigated in the solid monoclinic cr-phase (2' < 23.88 OK). The antiferromagnetic reflections of cr-0, (001) and (loo), containing the purely spin magnetic scattering on x-electrons, may give the values of f for sin 012 equaling to 0.1047 and 0.1242, respectively. The data of magnetic diffraction on KO, are also considered: in the magnetic structure proposed the antiferromagnetic reflections (001) and (110) (sin O/A is equal to 0.0735 and 0.1260, respectively) are again due to the orientation of the Tc-orbital spin moments (orbital moment is frozen). The whole set of obtained values f for 0, and 0; are in reasonable agreement with the calculated dependences of f.
