Magnetization M, specific heat 
, polarization P and dielectric constant 
of DyFeWO are investigated for the first time using a microscopic model and the Green’s function technique. The magnetic field dependence of M for temperatures below and above 
is observed. shows an anomaly at the Neel temperature which disappears by applying an external magnetic field h. P decreases with increasing h. The antiferromagnetic transition in DyFeWO is accompanied by a peak in . With increasing magnetic field the peak decreases, shifts to smaller values, and for strong magnetic fields vanishes. The magnetic field behaviour of P and is an evidence for the multiferroicity of DyFeWO. The observed results are in good qualitative agreement with the existing experimental data.
