Title: d=3 random field behavior near percolation

Abstract

The highly diluted antiferromagnet Mn{sub 0.35}Zn{sub 0.65}F{sub 2} has been investigated by neutron scattering for H>0. A low-temperature (T<11 K), low-field (H<1 T) pseudophase transition boundary separates a partially antiferromagnetically ordered phase from the paramagnetic one. For 1<H<7 T at low temperatures, a region of antiferromagnetic order is field induced but is not enclosed within a transition boundary. (c) 2000 American Institute of Physics.
