Phase transitions in a quasi-two-dimensional XY random magnetic system

Journal Article · · Phys. Rev. B: Condens. Matter; (United States)

The phase transitions of a randomly mixed quasi-two-dimensional antiferromagnet and ferromagnet Rb/sub 2/Mn/sub 1-//sub x/Cr/sub x/Cl/sub 4/ have been studied experimentally using ac susceptibility (chi), magnetization, and neutron scattering techniques. A characterization of the single crystals of Rb/sub 2/Mn/sub 1-//sub x/Cr/sub x/Cl/sub 4/ grown for this study is made with ac chi and electron-spin-resonance measurements. It turns out that the mixed system is a typical example of an XY magnet in the concentration range 0.1approx.
