Abstract

We report here the single‐crystal magnetic susceptibility data and the magnetic resonance behavior in the ordered state of (NH₃(CH₂)₂NH₃)CuBr₄, which is a strongly coupled, pseudo‐1D, Heisenberg antiferromagnet with strong in‐plane ferromagnetic coupling. The Neel temperature is 58 K and appears to be sample‐dependent. The observed resonances occur near g=2 with small anisotropies and suggest hidden spin canting with a second magnetic phase transition into a different ordered state at 20 K.
