Magnetic Ordering in (1-x)BaTiO₃-xLaFeO₃ Solid Solutions
R. Rajagukguk,D. G. Shin,B. W. Lee 한국자기학회 2011 Journal of Magnetics Vol.16 No.2
Solid solutions between BaTiO₃ and LaFeO₃ have been prepared through a solid state reaction method. The X-ray diffraction results reveal that Ba1-xLaxTi1-xFexO₃ (0.1 ≤ x ≤ 0.7) compounds have a cubic structure, whereas the parent material BaTiO₃ has a tetragonal structure. The magnetization measurements indicate that the materials have a magnetic ordering at room temperature and the magnetic properties of the solid solutions depending on the doping amount of LaFeO₃. The origin of magnetic behaviors is believed to be from Fe³? ions.
Irreversibility and Thermoremanent Magnetization in Y<SUB>0.8</SUB>Sr<SUB>0.2</SUB>MnO<SUB>3</SUB>
Agustina Ismail,W. Yansen,R. Rajagukguk,Y. M. Kwon,J. Kim,B. W. Lee 한국자기학회 2012 Journal of Magnetics Vol.17 No.3
Irreversible magnetization between the zero-field-cooled (ZFC) and field-cooled (FC) states in Y1-xSrxMnO3(x=0 and 0.2) was investigated. YMnO3 and Y0.8Sr0.2MnO3 have a hexagonal structure and the lattice parameter a decreases from 7.4408 A to 7.4327 A while c increases from 12.2244 A to 12.2287 A for YMnO3 and Y0.8Sr0.2MnO3, respectively. An anomaly is observed at around 74 K in ZFC and FC magnetization measurements for YMnO3, whereas in Y0.8Sr0.2MnO3 the σZFC and σFC are split at low temperature, indicating glass-like behavior.
