Resumen
A new approach to the experimental determination of the critical temperature of metamagnetic samples with non-zero demagnetizing factors is presented. The method is applied to metamagnetic Ni(NO3)2·2H2O, allowing the conclusion that this salt exhibits a tricritical point. Pressure dependence of the critical temperature, and the existence of a pressure-induced metamagnetic transition are also reported. © 1986.
