The 2 + 1 SU(3) Polyakov linear sigma model (PLSM) is used to investigate the respective influence of a finite volume and a magnetic field on the quark-hadron phase boundary in the plane of baryon chemical potential (μ_B) vs. temperature (T) of the QCD phase diagram. The calculated results indicate sizable shifts of the quark-hadron phase boundary to lower values of (μ_B and T) for increasing magnetic field strength, and an opposite shift to higher values of (μ_B and T) for decreasing system volume. Such shifts could have important implications for extraction of the thermodynamic properties of the QCD phase diagram from heavy ion data.
