Pressure and magnetic field effects on a quasi-2D spin-1/2 Heisenberg antiferromagnet

N. Barbero, T. Shiroka, C. P. Landee +3

Cu(pz)2(ClO4)2 (with pz denoting pyrazine, C4H4N2) is among the best realizations of a two-dimensional spin-1/2 square-lattice antiferromagnet. Below T_N = 4.21 K, its weak interla…
