The magnetic excitations of three ABX3-type quasi-l-D AFs with half-integer spin values are studied. We show that magnetic excitations in S = ~2 systems in the ordered phase at low T are excellently described by the semi-classical linear spin-wave theory. In S = ~ systems however, non-linear terms d
