Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons

open access: yesAdvanced Physics Research, EarlyView.
A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...

Path Integral Spin Dynamics for Quantum Paramagnets

open access: yesAdvanced Physics Research, EarlyView.
The study has developed a path integral method, which is a classical approach, combined with atomistic spin dynamics simulations to calculate thermal quantum expectation values. This method can handle Hamiltonians with non‐linear terms, which are important for describing uniaxial anisotropies and mechanical constraints.

Ferroelectric Control of Anisotropic Magnetoresistance in Ultrathin Sr2IrO4 Films toward 2D Metallic Limit

open access: yesAdvanced Physics Research, EarlyView.
Interfacing ferroelectric PbZr0.2Ti0.8O3 with ultrathin Sr2IrO4 tunes the antiferromagnetic Mott insulator into a 2D correlated metal. Switching the ferroelectric polarization induces nonvolatile, reversible resistance modulation in Sr2IrO4. The magnetoresisance in the heterostructure reveals the intriguing interplay of interfacial lattice coupling ...
