Recent progress in the field of multiferroics led to the discovery of manynew materials in which ferroelectricity is induced by cycloidal spiral orders.The direction of the electric polarization is typically constrained by spinanisotropies and magnetic field. Here, we report that the mixed rare-earthmanganite, Gd$_{0.5}$Dy$_{0.5}$MnO$_3$, exhibits a spontaneous electricpolarization along a general direction in the crystallographic ac-plane, whichis suppressed below 10 K but re-emerges in an applied magnetic field. Neutrondiffraction measurements show that the polarization direction results from alarge tilt of the spiral plane with respect to the crystallographic axes andthat the suppression of ferroelectricity is caused by the transformation of acycloidal spiral into a helical one, a unique property of this rare-earthmanganite. The freedom in the orientation of the spiral plane allows for a finemagnetic control of ferroelectricity, i.e. a rotation as well as a strongenhancement of the polarization depending on the magnetic field direction. Weshow that this unusual behavior originates from the coupling between thetransition metal and rare-earth magnetic subsystems.
