Witryna24 gru 1999 · Abstract. The spin dynamics of an arbitrary localized impurity in an insulating two-dimensional antiferromagnet, across the host transition from a paramagnet with a spin gap to a Néel state, is described. The impurity spin susceptibility has a Curie-like divergence at the quantum-critical coupling, but with a universal … WitrynaLosartan Potassium is used for hypertension, including in people with left ventricular hypertrophy and kidney dysfunction among type II diabetics.
