Ferromagnetic Phase Transition of DPPH Induced by a Helical Magnetic Field

Overview

This repository contains the full research package for the study:

"Ferromagnetic Phase Transition of DPPH Induced by a Helical Magnetic Field"

The work presents experimental evidence of an anomalous magnetic response in DPPH under a helical magnetic field configured at the magic angle (~54.74°), suggesting a transition from paramagnetic to weakly ferromagnetic behavior at room temperature.
