The rare-earth chromates (RECrO$_3$) and manganites (REMnO$_3$) where, RE =Eu, Y, Dy, Ho, Gd are constantly under scrutiny in search of room temperaturemagnetoelectric multiferroics. However, the artefacts and undesirable signal insome of the measurements pose a severe challenge in confirming theferroelectric (FE) phase, especially in reference to pyroelectric currentmeasurement technique. In this regard, we propose a simple modified approach topyroelectric current measurement named as 4-segment thermal cycling protocol.This protocol assists in isolating the elusive, irreversible thermallystimulated current from the currents associated with spontaneous and reversiblenature of the electric polarization in FE phase. In order to explain workingprinciple of the protocol, we have compared simulated response of twohypothetical materials; an FE material free of space charges and a paraelectricmaterial possessing only space charges. Further, we experimentally verify thesenew protocols in a single crystal of prototype ferroelectric material, GlycinePhosphite. This report primarily focuses on detailed investigation offerroelectricity using the proposed protocol in two polycrystalline materials,HoCrO$_3$ and DyFe$_{0.5}$Mn$_{0.5}$O$_3$ where, the former has been reportedto be multiferroic earlier. Our elaborative and careful approach topyroelectric studies expound on the absence of reversible spontaneous electricpolarization at temperature ranges tested in both, HoCrO$_3$ andDyFe$_{0.5}$Mn$_{0.5}$O$_3$.
