We have made an attempt to study the second‐order magnetic phase transition in Cr/TbDyFe ultrathin film multilayers by characterizing it with the help of critical exponents deduced from magnetization measurements. The thickness of these films falls in the monolayer range and hence each of these films could be approximated to systems with a lattice dimensionality of two. However, we ended up with the critical exponent values close to those for a three‐dimensional Heisenberg spin system. The reasons for this could be attributed to the interactions between spins coupled through the interlayer of Cr.
