Re-entrant spin susceptibility of a superconducting grain
We study the spin susceptibility chi of a small, isolated superconducting grain. Because of the interplay between parity effects and pairing correlations, the dependence of chi on temperature T is qualitatively different from the standard BCS result valid in the bulk limit. If the number of electrons on the grain is odd, chi shows a re-entrant behavior as a function of temperature. This behavio...
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 کاملRe-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 کاملRe-entrant DNA gels
DNA is acquiring a primary role in material development, self-assembling by design into complex supramolecular aggregates, the building block of a new-materials world. Using DNA nanoconstructs to translate sophisticated theoretical intuitions into experimental realizations by closely matching idealized models of colloidal particles is a much less explored avenue. Here we experimentally show tha...
