# Unconventional magnetic order in the conical state of MnSi

## TL;DR

This paper investigates the magnetic structures in MnSi, revealing that the conical phase's magnetic order varies significantly with field direction and differs from traditional models, especially near the critical temperature.

## Contribution

It provides new insights into the magnetic structure of MnSi's conical phase, highlighting unconventional behavior influenced by field orientation.

## Key findings

- Magnetic structure in the conical phase depends on field direction.
- Deviations from conventional conical magnetic order are observed.
- Unconventional magnetic behavior is prominent near Tc.

## Abstract

In the temperature-magnetic field phase diagram, the binary metallic compound MnSi exhibits three magnetic phases below Tc ~ 29 K. An unconventional helicoidal phase is observed in zero field. At moderate field intensity a conical phase sets in. Near Tc, in an intermediate field range, a skyrmion lattice phase appears. Here we show the magnetic structure in the conical phase to strongly depend on the field direction and to deviate substantially from a conventional conical structure.
