Abstract The magnetic susceptibility measurements on layered type structure ( CH 3 NH 3 ) 2 FeCl 2 Br 2 revealed a transition temperature T N ( H = 0) ≈ 100 K . The transition temperature of ( CH 3 NH 3 ) 2 FeCl 4 was previously found to be T N ( H = 0) ≈ 95 K . The effect of magnetic field on the transition temperature and peak intensity for both compounds has been investigated.
