🧲 Spintronics WASM Demo

Real-time Magnetization Dynamics in Your Browser

About This Demo

This demonstration runs physics-accurate spintronics simulations entirely in your browser using WebAssembly. The simulation solves the Landau-Lifshitz-Gilbert (LLG) equation in real-time, showing how magnetic moments precess and relax in response to external fields.

🎯 Demo 1: Single Spin Precession

Visualize magnetization precession around an applied magnetic field

H_x (kA/m): 0

H_y (kA/m): 0

H_z (kA/m): 10

Damping α: 0.01

Time: 0.000 ns

M_x: 0.000

M_y: 0.000

M_z: 1.000

|M|: 1.000

🌊 Demo 2: Magnon Propagation in Spin Chain

Watch spin waves (magnons) propagate through a 1D chain of coupled spins

Chain Length: 50

Excitation Position: 25

Amplitude: 0.5

Time: 0.000 ns

Spins: 50

⚡ Demo 3: Spin Hall Effect Calculator

Calculate spin current generation from charge current

Charge Current Density (10¹⁰ A/m²):

Spin Hall Angle θ_SH:

Result:

Spin Current Density: — A/m²

The spin Hall effect converts charge current into transverse spin current. This is a key mechanism for electrical manipulation of magnetization in spintronic devices.
