The temperature dependence of the dc magnetization and specific heat capacity are systematically investigated for perovskite YbCrO3 chromites. results show that there exist two complex sequences magnetic transitions with characteristics reversal Yb3+/Cr3+ spin ordering at different temperature, respectively. antiferromagneticlike transition around TN=118 K is attributed to antiferromagnetic Cr3+ spins a negative magnetization, accompanied tendency plateau below 10 caused by Yb3+ ordering. We...
In this work, we have fabricated a series of perovskite-type oxide LaFeO<sub>3</sub> samples using simple sol–gel method and further calcination treatment.
Abstract Single-phase HoCrO3 samples were prepared using the conventional solid-state reaction. The temperature dependence of dc magnetic properties show that ZFC and FC magnetization curves are irreversible strongly nearly symmetrical below 141.0 K under 100 Oe. Moreover, there appears a novel behavior with negative (diamagnetism-like) characteristics. This exhibits coexistence canted antiferromagnetic weak ferromagnetic phase existence competition mechanism Tc1 = K. In addition, it is also...
Exploration of rare-earth (RE)-based Kagomé lattice magnets with spin-orbital entangled jeff = 1/2 moments will provide a new platform for investigating the exotic magnetic phases. Here, we report family RE3BWO9 (RE Pr,Nd,Gd-Ho) boratotungstates RE3+ ions arranged on and perform its structure characterizations. These serial compounds crystallize in hexagonal coordinated space group P63 (no. 173), where have distorted connections within ab plane stacked an AB-type fashion along c axis. The...
Oxygen vacancies have a profound effect on the magnetic, electronic, and transport properties of transition metal oxides but little is known about their thermal expansion. Herein we report oxygen defects structure formation expansion layered perovskite Ca 2 RuO 4 (CRO). It shown that CRO containing excess crystallizes in metallic L -CRO phase without from 100 K to 500 displays normal behavior, whereas those with adopt at room temperature an insulating S exhibit enormous negative (NTE) 360 K,...
We have demonstrated a novel three-dimensional (3D) architecture of graphene/carbon nanotube (G-CNT) hybrid synthesized at large scale within just 5 s via simple microwave-heating method without the usage any other conducting or expanding agent for first time. The carbon composites obtained consist evenly grown CNTs with an average diameter about 15 nm on surface graphene nanosheets. G-CNT exhibits enhanced electrochemical performance both aqueous and organic supercapacitor devices....
