Magnetic properties of rare earth HoCrO3 chromites
Abstract：The temperature dependence of the magnetic properties was systemically studied by dc/ac magnetization and specific heat measurement for heavy rare earth HoCrO3 chromites.The results revealed the existence of complex phase coexistence and competitive magnetic behavior in HoCrO3 chromites.It was found that,in the region of higher temperature above 141.0 K,HoCrO3 behaved as a typical Cufie-Weiss paramagnetic (PM).And in the region of low temperature,a novel magnetization behavior was observed with negative magnetization (diamagnetism-like) characteristics under an external field of 100 Oe and M-Tcurves exhibited two symmetrical branches for field cooling (FC) and zero field cooling (ZFC) modes.This behavior indicated the coexistence of canted antiferromagnetic (CAFM) and weak ferromagnetic (FM) phase.These also exhibited the existence of competition mechanism below characteristic temperature TN1=141.0 K and the magnetic order of Ho ion below 7.5 K.The current complex magnetization might be attributed to the interaction between paramagnetic Ho3+moments and canted Cr3+ moments. 作者： Author： SU Yuling[1] ZHANG Jincang[2] FENG Zhenjie[2] LI Zijiong[1] SHEN Yan[1] CAO Shixun[2] 作者单位： Department of Physics, Zhengzhou University of Light Industry, Zhengzhou 450002, ChinaDepartment of Physics, Shanghai University, Shanghai 200444, China 期 刊： 稀土学报（英文版） ISTICEISCI Journal： Journal of Rare Earths 年，卷(期)： 2011, 29(11) 分类号： P618.7 Keywords： rare earth chromites phase coexistence magnetic interaction 机标分类号： F2 O4 机标关键词： temperature dependence competition mechanism magnetic properties higher temperature phase coexistence heat measurement low temperature external field complex region interaction rare earth negative typical results order novel found dc/ac two 基金项目： the National Natural Science Foundation of China，the Science & Technology Committee of Shanghai Municipality， the Natural Science Foundation of Henan Province，the Doctoral Innovation Fund of Zhengzhou University of Light Industry Magnetic properties of rare earth HoCrO3 chromites[期刊论文] 稀土学报（英文版） --2011, 29(11)The temperature dependence of the magnetic properties was systemically studied by dc/ac magnetization and specific heat measurement for heavy rare earth HoCrO3 chromites.The results revealed the existe...【Magnetic properties of rare earth Ho】相关文章：
