The phase diagrams and magnetization curves of a diluted mixed spin‐1/2 and spin‐1 Ising system on honeycomb lattice in a transverse field Ω are investigated by the use of the effective‐field theory with correlations. The influence of Ω on the magnetic properties is discussed and some interesting phenomena are found in them, such as the transverse field induced magnetic ordering in the system with a concentration at or very near the critical concentration where the system with Ω = 0 becomes paramagnetic.
