Re-entrant spin glass and Magnetoresistance in Co0.2Zn0.8Fe1.6Ti0.4O4 spinel oxide
We have investigated the static and dynamical response of magnetic clusters in Co0.2Zn0.8Fe1.6Ti0.4O4 spinel oxide, where a sequence of magnetic phase transitions, i.e, paramagnetic(PM) to ferromagnetic (FM) state at TC ≤ 270K and ferromagnetic to canted spin glass (CSG) state at Tf ≤ 125K is observed. The time dependence of remanent magnetization shows a non-equilibrium spin dynamics in the CS...
متن کاملStatic critical exponents of the ferromagnetic transition in spin glass re-entrant systems.
The static critical phenomenology near the Curie temperature of the re-entrant metallic alloys Au(0.81)Fe(0.19), Ni(0.78)Mn(0.22), Ni(0.79)Mn(0.21) and amorphous a-Fe(0.98)Zr(0.08) is studied using a variety of experimental techniques and methods of analysis. We have generally found that the values for the exponents α, β, γ and δ depart significantly from the predictions for the 3D Heisenberg m...
متن کاملObservation of re-entrant spin reorientation in TbFe1−xMnxO3
We report a spin reorientation from Γ4(Gx, Ay, Fz) to Γ1(Ax, Gy, Cz) magnetic configuration near room temperature and a re-entrant transition from Γ1(Ax, Gy, Cz) to Γ4(Gx, Ay, Fz) at low temperature in TbFe1-xMnxO3 single crystals by performing both magnetization and neutron diffraction measurements. The Γ4 - Γ1 spin reorientation temperature can be enhanced to room temperature when x is around...
متن کاملSpin Singlet State in Heptamers Emerging in Spinel Oxide AlV2O4
We present our theoretical results on the electronic state in vanadium spinel oxide AlV2O4. The material is a mixed-valent system with the average valence V, and V cations constitute a frustrated pyrochlore structure. It shows a structural transition at ∼ 700 K, leading to the formation of seven V-sites clusters — heptamers. We study the electronic state of the heptamer by explicitly taking acc...
متن کاملMAGNETIC ORDERING IN RE-ENTRANT (PdFe)Mn STUDIED BY AC SUSCEPTIBILITY AND MAGNETORESISTANCE MEASUREMENTS
The linear and non-linear magnetic response and the low field magnetoresistive anisotropy of re-entrant (=Fe)Mn have been measured near both "candidate" transitions. The concensus of current experimental data is that while the entire magnetic response of a ferromagnet is singular 1 h2 XF (h, t) = t-y.G h tr+@ N + . . .
