High-field magnetization measurements have been performed up to 56 T for a two-dimensional S = 1/2 frustrated square-lattice antiferromagnet (CuCl)LaNb 2 O 7 , a recently discovered spin gap system (Δ/ k B = 26.7 K). It is found that the spin gap cl

We report on the magnetic properties of double-layered perovskite (CuCl)LaNb 2 O 7 with a square lattice of S =1/2 Cu 2+ ions, prepared by topotactic ion-exchange reactions. Magnetic susceptibility exhibits a thermal-activated behavior, and the analy

A 1/3 magnetization plateau was recently observed in the layered perovskite $(\text{CuBr}){\text{Sr}}_{2}{\text{Nb}}_{3}{\text{O}}_{10}$ with $S=1/2$ CuBr layers. In order to control the cell size and thus exchange parameters, we have prepared an iso

A new triple-layered perovskite (CuBr)Sr 2 Nb 3 O 10 with the S = 1/2 square lattice has been prepared through a chimie douce route. Presence of strong spin frustration is inferred from zero-field specific heat measurements which exhibit successive p

Magnetic susceptibility, heat capacity, high-field magnetization and neutron diffraction measurements have been performed on a two-dimensional S ¼ 1=2 square-lattice system (CuBr)LaNb2O7, prepared by a topotactic ion-exchange reaction of a nonmagnet
