Neutron spin echo spectroscopy under 17T magnetic field at RESEDA

TL;DR

This paper demonstrates that neutron spin echo spectroscopy using MIEZE can operate effectively under magnetic fields up to 17T at RESEDA, maintaining high resolution and enabling studies of field-dependent phenomena in condensed matter physics.

Contribution

It provides proof-of-principle that high magnetic fields can be applied without degrading resolution in neutron spin echo measurements using MIEZE at RESEDA.

Findings

High magnetic fields up to 17T are compatible with MIEZE-based neutron spin echo.

The resolution remains unchanged across the magnetic field range tested.

This enables future studies of magnetic field-driven phase transitions.

Abstract

We report proof-of-principle measurements at the neutron resonance spin echo spectrometer RESEDA (MLZ) under large magnetic fields by means of Modulation of IntEnsity with Zero Effort (MIEZE). Our study demonstrates the feasibility of applying strong magnetic fields up to 17\,T at the sample while maintaining unchanged sub-$\mu$eV resolution. We find that the MIEZE-spin-echo resolution curve remains essentially unchanged as a function of magnetic field up to the highest fields available, promising access to high fields without need for additional fine-tuning of the instrument. This sets the stage for the experimental investigation of subtle field dependent phenomena, such as magnetic field-driven phase transitions in hard and soft condensed matter physics.
