Title:
Magnetic-Field Induced Instability Surrounding the {{A}}-Phase of {{MnSi}}: {{Bulk}} and {{SANS}} Measurements 
Abstract:
We have determined the boundary of the magnetic A-phase of MnSi from distinct changes of slope in the AC susceptibility for magnetic field B applied parallel to the crystallographic h1 0 0i, h1 1 0i and h1 1 1i directions. The specific heat displays an anomaly of a few percent at the border of the A-phase characteristic of a well-defined phase transition. In addition to the previously reported change of orientation of the helical modulation in the A-phase, we observe a gradual appearance of a ri...    »
