The magnetic susceptibility of the spin-glass state that may appear in an itinerant-electron antiferromagnet containing magnetic impurities has been calculated as a function of the temperature. The spin–spin interaction mediated by the condensed electrons has been calculated and a short-range interaction of the form (cos 2k0r/r2)e−r/ξ0 has been obtained. A percolation mechanism has been used in order to explain the occurrence of the spin-glass state.

Evidence of the coexistence of an ordered antiferromagnetic and a spin glass state is given by studying a polycrystalline Tb2CuIn3 sample with neutron diffraction in a non-magnetic and a magnetic environment. Tb2CuIn3 is an antiferromagnet with competing exchange interactions (J1> 0 for nearest neighbours and J2 < 0 for next nearest neighbours) and an ordering temperature TN =33 ± 1 K. Powder diffraction measurements reveal a broad diffuse peak - due to short-range magnetic order - underneath the (100) long-range order magnetic Bragg reflection. The exposure of the sample in magnetic fields up to 7.5 T, under both zero field and field-cooled conditions, show that neither the long-range magnetic order nor the short-range order are destroyed by the outer magnetic fields. The almost field independent behaviour of the magnetic intensities is explained by the existence of a spin glass state. Support on the simultaneous presence of antiferromagnetic and spin glass states is given by recent ac-dc magnetic measurements. The infinite range model for spin glasses with strong uniaxial anisotropy has predicted this kind of magnetic behaviour.
