| Abstract | The antiferromagnetism in α-Cu3Mg(OH)6Br2 was studied by magnetic-susceptibility, specific-heat, and neutron-diffraction measurements. The crystal structure consists of Cu2+ kagome layers with Mg2+ ions occupying the centers of the hexagons, separated by Br1-ions. The magnetic system orders antiferromagnetically at 5.4 K with the magnetic moments aligned ferromagnetically within the kagome planes. The ordered moment is 0.94μB, suggesting little quantum and geometrical fluctuations. By comparing the magnetic and specific-heat properties with those of the haydeeite, we suggest that α-Cu3Mg(OH)6Br2 may be described by the two-dimensional spin-1/2 Heisenberg kagome model and is in the region of the ferromagnetic-order side of the phase diagram. © 2019 American Physical Society. |
