Abstract
The disordered antiferromagnet PbFeNbO is investigated in a wide temperature range by combining Mössbauer spectroscopy and neutron diffraction experiments. It is demonstrated that the magnetic ground state is a microscopic coexistence of antiferromagnetic and spin-glass orders. This speromagnetlike phase features frozen-in short-range fluctuations of the Fe magnetic moments that are transverse to the long-range ordered antiferromagnetic spin component.
