Powder magnetic susceptibility measurements were obtained for [NH3(CH2)xNH3]CuCl4xBr(4(1-x)with various chloride and bromide concentrations (n= 5 or 7, and xbetween 0 and 1). Although the pure bromide compounds, x= 0, are three dimensional ferromagnets, while the pure chloride compounds, x= 1, are three dimensional antiferromagnets, no spin glass behavior was observed. Temperature versus composition phase diagrams showing possible tetracitical points with mixed phases were constructed for both series of compounds and are discussed. |
