The spin dynamics of the spin-1/2 triangular-lattice antiferromagnet Cs₂CuBr₄ is probed by means of high-frequency electron paramagnetic resonance (EPR) spectroscopy. Temperature dependences of EPR parameters are studied ...

In this article I review recent achievements on experimental studies of magnetic excitations in the copper pyrimidine dinitrate [PM–Cu(NO₃ )₂ (H ₂O) ₂ ]n (PM = pyrimidine), an S = 1/2 antiferromagnetic chain material with ...
