چکیده
A statistical mechanical model for the switching mechanism of photoinduced magnetization is proposed making use of dynamics of magnetization in the circumstance with the metastable structure. As a typical model with metastability, the equilibrium and nonequilibrium properties of the Blume-Capel (BC) model have studied. We demonstrate reversible changes of magnetization corresponding to the change of system parameters, which would model the reversible photo-induced magnetization.

By studying the dynamics of the metastable magnetization of a statistical mechanical model we propose a switching mechanism of photoinduced magnetization. The equilibrium and nonequilibrium properties of the Blume-Capel (BC) model, which is a typical model exhibiting metastability, are studied by mean field theory and Monte Carlo simulation. We demonstrate reversible changes of magnetization in...
متن کاملUltrafast photoinduced phase separation dynamics in Pr0.6Ca0.4MnO3 thin films
The time resolved Magnetooptical Kerr effect in the substrate-strain-induced insulating ferromagnetic phase in (Pr0.6Ca0.4)MnO3 thin films on two different substrates was measured in a magnetic field up to 1.1T. The photoinduced Kerr rotation and ellipticity show remarkably different magnetic-field dependence. From the comparison of the magnetic field dependencies of the photoinduced and static...
متن کاملDoping-Induced Ferromagnetism and Possible Triplet Pairing in d Mott Insulators
We study the effects of electron doping in Mott insulators containing d ions such as Ru, Os, Rh, and Ir with J = 0 singlet ground state. Depending on the strength of the spin-orbit coupling, the undoped systems are either nonmagnetic or host an unusual, excitonic magnetism arising from a condensation of the excited J = 1 triplet states of t42g . We find that the interaction between J-excitons a...
متن کاملElectric-Field-Induced Triplet to Singlet Transition in Size-2 Trigonal Zigzag Graphene Nanoflake
Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...

The filled skutterudite compound PrOs4Sb12 exhibits superconductivity below a critical temperature Tc = 1.85 K that develops out of a nonmagnetic heavy Fermi liquid with an effective mass m∗ ≈ 50 me, where me is the free electron mass. Analysis of magnetic susceptibility, specific heat, electrical resistivity and inelastic neutron scattering measurements within the context of a cubic crystallin...
