Magnetic and electrical studies of Ho0.9RE0.1CrO3 (RE = Gd and Yb) multiferroics

SummaryWe report magnetic and electrical studies on multiferroic systems Ho0.9(RE)0.1CrO3 where RE symbolizes rare earths like Gd and Yb. Solid state diffusion method has been used to synthesize the samples. Structural phase formation has been confirmed with the help of powder X-ray diffraction. Magnetization measurements show canted antiferromagnetic nature with a weak ferromagnetic phase. Néel temperature for Cr3+-Cr3+ ordering shifts to higher side with increasing radii of rare earth cations. Frequency (100 Hz to 1 MHz) and temperature (300-650 K) dependent resistivity measurements are suggestive of semiconducting nature of the samples.
