The different magnetic behaviors of LaCoO$_3$ films grown on LaAlO$_3$ and SrTiO$_3$ are related to the Co-O-Co bond angles and the constraints imposed on the Co-O bond lengths by the substrate geometries. Long-range magnetic order occurs below T ~ 9

Optical birefringence studies of the randomly diluted, $d=3$ Ising antiferromagnet ${\mathrm{Fe}}_{0.6}$${\mathrm{Zn}}_{0.4}$${\mathrm{F}}_{2}$ reveal that the magnetic specific heat exhibits a symmetric logarithmic singularity, consistent with an ef

It has long been believed that equilibrium random-field Ising model (RFIM) critical scattering studies are not feasible in dilute antiferromagnets close to and below T{sub c}(H) because of severe nonequilibrium effects. The high magnetic concentratio
