N2 - An electron paramagnetic resonance (EPR) study in polycrystalline magnetoelectric Y CrO3 is carried out at the X-band (8.8-9.8GHz) in the 85-300K temperature range. For all the temperatures, the EPR spectra show a single broad line attributable to Cr3+ (S=3/2) ions. The onset of the antiferro-paramagnetic transition has been determined from the temperature dependence of parameters deduced from the EPR spectra: the integrated intensity (IEPR), the g-factor and the peak-to-peak linewidth (ΔHpp). Below 140K, a weak ferromagnetism is observed and it is attributed to canting of Cr 3+ ion sublattices in the antiferromagnetic matrix. Low-field microwave absorption (LFMA) is used to give further knowledge on this material; where this technique also gives evidence of the magnetic order, suggesting a weak ferromagnetism at low temperature.
