  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.
